685I Visual Liquid Level Indicator for Atmospheric Vessels

ApplicationThe Model 685I is a liquid head pressure type level indicator. It con-tinuously indicates the liquid level in an atmospheric (vented) tankin feet and inches. Also, the scale on the Model 685I is availablecalibrated for horizontal cylindrical vessels in pounds, gallons, bar-rels, percent, etc.

Features• Simple Adjustments: Zero Adjustment Knob and one Specific

Gravity (span) Knob. Unit can be factory calibrated for a nominalcost or field adjusted in less than 15 minutes, without having tochange the liquid level in the vessel.

• Easy to Read: Scale reads the same as a hand tank gauge, mak-ing it unnecessary to convert psig of head pressure into feet andinches of liquid to get the correct reading.

• Long Life: All bearings are Teflon®, Delrin® or Moly Disulphidebaked on Dry Film Lubricated Stainless Steel.

Operation Liquid head pressure against a flexible elastomer diaphragm istransmitted directly to a leaf spring, which has a fixed pivot point atthe upper end and an adjustable fulcrum point in the mid region ofthe leaf spring. For example, because 8’ of heavy liquid exerts morepressure on the diaphragm than 8’ of lighter liquid, the spring canbe "stiffened" by moving the fulcrum down by the gravity adjust-ment knob (red), so the indicator will still read 8’. The zero knob(green) moves the entire spring assembly and pointer, having thesame effect as shifting the scale.

InstallationSince the unit measures liquid head pressure, the point at which it isinstalled on the vessel is the point that liquid measurement begins.For calibration and maintenance purposes, always install an isolationvalve between the model 685I and the vessel. Also, install a drainpetcock in the liquid inlet bottom, where a plug is generally located.

685S Single Switch Liquid Level Indicator for Atmospheric VesselsApplicationThe Model 685S is a liquid head pressure type level control. It con-tinuously indicates the liquid level in an atmospheric vessel in feetand inches. It has an adjustable switch which completes an electri-cal circuit to a solenoid, alarm, or other device when the level risesto the top predetermined point, and breaks the circuit when the levelfalls to the bottom predetermined point (or the reverse). In addition,the scale on the Model 685S is available calibrated for horizontalcylindrical vessels in pounds, gallons, barrels, percent, etc.

Features• Simple Adjustments: One high adjustment dial for top level set point

and one low dial for bottom level set point. One Zero AdjustmentKnob and one Specific Gravity (span) Knob. Unit can be factory cal-ibrated for a nominal cost or field adjusted in less than 15 minutes,without having to change the liquid level in the vessel.

• Easy to Read: Scale reads the same as a hand tank gauge, mak-ing it unnecessary to convert psig of head pressure into feet andinches of liquid to get the correct reading.

• Long Life: All bearings are Teflon®, Delrin® or Moly Disulphidebaked on Dry Film Lubricated Stainless Steel.

• Weather Proof and Explosion Proof Housing.

Operation Liquid head pressure against a flexible elastomer diaphragm is trans-mitted directly to a leaf spring, which has a fixed pivot point at theupper end and an adjustable fulcrum point in the mid region of the leafspring. For example, because 8’ of heavy liquid exerts more pressure onthe diaphragm than 8’ of lighter liquid, the spring can be "stiffened" bymoving the fulcrum down by the gravity adjustment knob (red), so theindicator will still read 8’. The zero knob (green) moves the entirespring assembly and pointer, having the same effect as shifting thescale. The switch trigger assembly is normally independent of the indi-cator mechanism and is free to tilt around the fixed pivot, except thatit is weighted to assure a vertical position. At high or low levels, thetrigger assembly tilts; thus actuating the cam and engaging the switch.

InstallationSince the unit measures liquid head pressure, the point at which itis installed on the vessel is the point that liquid measurementbegins. For example, if the unit is mounted 1 foot above the bottomof an 8’ vessel, the liquid level from the bottom to the 1’ mountingwill not be measured (or seen); therefore, the indicator should be"zeroed" at 1’ and the specific gravity knob should be calibratedaccordingly ie. 1 to 8 feet or total of 7 foot span. For calibration andmaintenance purposes, always install an isolation valve betweenthe model 685S and the vessel. Also, install a drain petcock in theliquid inlet bottom, where a plug is generally located.

685S Multiswitch Liquid Level Indicator for Atmospheric VesselsApplicationThe Model 685S Multiswitch is a liquid head pressure type control,which continuously indicates the liquid level and supplies on and offsignal as adjusted. Each switch may be set at different set points tocontrol a separate device, such as an auxiliary or motor controlrelay, alarms, etc.

Features• Easy to read: Scale reads the same as a hand tank gauge, mak-

ing it unnecessary to convert psig of head pressure into feet andinches of liquid to get the correct reading.

• Special Scales: Gallons, Pounds, Percent, etc. is available.• Long Life: All bearings are Teflon®, Delrin® or Moly Disulphide

baked on Dry Film Lubricated Stainless Steel.• Weather Proof and Explosion Proof Housing.

685E Electric Liquid Level Indicator for Atmospheric VesselsApplicationThe Model 685E Liquid Level Transmitter is an electro-mechanicallevel control device, which accomplishes three (3) main functions.These are remote indication, local liquid level indication, and hi-lowadjustable switch outputs. The unit continuously indicates the liquidlevel and transmits a proportional signal.

Features• Complementary Adjustments: Zero and Span adjustments at transmitter.• Easy to Read: Scale reads the same as a hand tank gauge, mak-

ing it unnecessary to convert psig of head pressure into feet andinches of liquid to get the correct reading.

• Special Scales: Gallons, Pounds, Percent, etc. is available.• Long Life: All bearings are Teflon®, Delrin® or Moly Disulphide

baked on Dry Film Lubricated Stainless Steel.• Weather Proof and Explosion Proof Housing.

Operation Liquid head pressure against a flexible elastomer diaphragm istransmitted directly to a leaf spring, which has a fixed pivot point atthe upper end and an adjustable fulcrum point in the mid region ofthe leaf spring. For example, because 8’ of heavy liquid exerts morepressure on the diaphragm than 8’ of lighter liquid, the spring can be"stiffened" by moving the fulcrum down by the gravity adjustmentknob (red), so the transmitter will still read 8’. The zero knob (green)moves the entire spring assembly and pointer, having the sameeffect as shifting the scale. The movement of the pointer rotates ashaft extending into the explosion proof housing where the electron-ic transmitter and switches are located. The shaft drives a poten-tiometer, thereby giving a continuous signal to the plug-in amplifier.The proportional signal is then transmitted to the remote indicatingdevice in proportion to the liquid level which exists in the tank.

InstallationSince the unit measures liquid head pressure, the point at which it isinstalled on the vessel is the point that liquid measurement begins.For calibration and maintenance purposes, always install an isolationvalve between the model 685E and the vessel. Also, install a drainpetcock in the liquid inlet bottom, where a plug is generally located.

With no liquid head pressure on the unit, adjust GREEN knob sopointer reads the height of the unit inlet connection above tankbottom. (Example: If the center of the connection is 1 foot abovetank bottom, adjust GREEN knob so pointer reads 1 foot.)

1. Open 2 inch inlet valve so liquid head pressure is on the unit.note pointer reading on scale. (Example: pointer indicates 6 feet.)

2. Hand gage tank. Best results will be obtained if tank is at least 2/3full. (Example: Tank gages 8 feets.)

3. Relieve liquid head pressure from unit by closing 2 inch valve andremoving 1/2 inch drain plug from bottom of inlet connection.

4. Readjust GREEN knob per (A) above.5. Turn RED knob several turns to the LEFT. (Note: Turning the RED knob with head pressure on the unit may give erroneous reading.)6. Apply tank head pressure to the unit again. (Example: Pointer now

indicates 7 feet.)7. REPEAT the process until pointer indicates same reading as hand gage.

Features• Dependable: Factory-sealed snubber assembly eliminates the

possibility of orifice plugging from foreign matter.

• Effective: Rapid pulsation pressure peaks up to 30 psig result-ing in no visible pointer motion.

• Cost Saving: The Snubber eliminates the necessity of a sepa-rate tank connection and field wiring from the pump unit to theLevel Control. The Level Control can be shop mounted andwired on a pump unit skid at a considerable saving in fieldinstallation cost.

Operation Pressure on the upstream diaphragm forces the silicone oilthrough the orifice and against the downstream diaphragm. Theorifice slows the rate of movement of silicone oil. If the head onthe upstream diaphragm is suddenly increased from zero to 16’, ittakes 45 seconds for the pointer to reach the 16’ reading. There isno disadvantage to this slowdown, since in normal operation ittakes hours for the tank to fill from zero to 16’. The Snubber willoperate satisfactorily at all ambient temperatures due to thealmost flat viscosity-temperature curve of the silicone oil.

Installation (Snubber to 685)1. Remove the three cap screws attaching the housing adapter to

the level control housing.

2. Remove the diaphragm.

3. Insert the Snubber between the adapter and the housing withthe convex (protruding) diaphragm exposed to the liquid.

4. Install the three long screws furnished with the Snubber.NOTE: Due to the slow action of the pointer when a Snubber isused, the Level Control can be calibrated more quickly if theSnubber is first removed. Installation of the Snubber will notaffect calibration of the Level Control.

Installed and field calibrated in justminutes, as no intrusion into the tank isrequired. Add the optional Hi-Lowswitches for pump functions or alarmpoints, or even a 4 to 20 milliampsignal to give you completecontrol over your fluid levels.

The Series 685 features an explosion-proof housing for added safety.

Vessel connections are available inan array of styles and materials.

790 Horizontal Level Control Floatswitch

ApplicationThe Model 790 Floatswitch is a side-mounted liquid level switchwhich works on positive magnetic repulsion to complete an electri-cal circuit to a pump, valve, alarm or other device, when the liquidlevel in the vessel rises (or lowers) to a predetermined point.

Features• Corrosion Resistant: All wetted parts are 316 Stainless Steel.

• Variety of Switch Options: SPDT, DPDT, High Amp, High Temp.

• Explosion Proof: CSA APPROVEDClass I, Groups C & DClass II, Groups E, F & GClass III, Enclosure Type 4X

• External Chamber Available: Carbon Steel with (2) 1" NPTConnections.

Operation A magnet is permanently welded into the float arm assembly; asthe liquid in the vessel rises, moving the float up, the float arm piv-ots (down) repelling another magnet inside the 790 unit, causingsnap action of the electrical switch. Since SPDT switches are uti-lized, the level switch can simply be wired to energize at either ahigh or low level position.

Electrical Contacts: SPDT Micro Switch, Standard.

683Section No. 2.2

683 Floatswitch for Atmospheric Vessels up to 2 psig

ApplicationThe Model 683 Floatswitch is a float type control which com-pletes an electrical circuit to a pump, valve, alarm or other device,when the liquid level in the vessel rises (or lowers) to a prede-termined point.

Features• Corrosion Proof: Float and Arm are 304 S.S., Cad Plated Steel

Vessel Connection (Other materials available for more corrosiveliquids).

• No Wearing Parts: Due to the pivoting action of the float arm onthe diaphragm, sticking does not occur in thick or corrosive liquids.

• Variety of Switch Outputs: The 683 can be obtained with mercu-ry or micro switch output and in various combinations, ie. SPST,SPDT, DPDT, etc.

• Adjustments: Nothing to adjust or get out of calibration on themercury switches. Micro switches can be adjusted from the out-side when the floatswitch is installed on the vessel.

• Simple Installation: On an INTERNAL MOUNT, the float passesthrough a 2" nipple. On an EXTERNAL MOUNT, install on 2" exter-nal pipe riser connected to the pressure vessel above the highlevel and below the low level control points.

• Longer Life: Since there are no wearing parts, the replacement ofstuffing boxes, etc. is eliminated.

Operation The float arm passes through a nylon reinforced diaphragm with aspecial nut on each side of the diaphragm; the switches areattached to the float arm by means of stainless steel supports. Thediaphragm acts as a pivot point for the float arm, and as a sealbetween the vessel and the explosion proof switch housing. Themaximum travel of the float between the switch “make” and"break" is 1" for mercury switches and 1/4" for micro switches.

688 Level Switch for Pressure Vessels up to 2000 psig

ApplicationThe Model 688 is a single point on/off level switch, which com-pletes an electrical circuit to a pump, valve, alarm or otherdevise. This unit senses virtually any liquid and does not needadjustment when the vessel contents are changed. It will ignorefoam, surge or splash to indicate true liquid level, with repeata-bility to 0.050 in. standard.

Features• Fail-Safe: Unit is field adjusted to high or low level fail-safe

conditions.• Auto Test Self-Checking: The unique self-checking feedback loop

constantly "proves" that the switch is working properly andoffers superior reliability in critical applications.

• Long Life: The all stainless steel, heavy-duty sensor resists damagefrom product abrasion or corrosion. No packing glands are used.

• Explosion Proof: CSA Approved for Class I Group C & D, Class IIGroup E, F and G hazardous locations

• Versatile Power Supply: The standard units are designed toaccept 115 VAC, 230 VAC or low voltage AC or DC input power.

Operation When liquid touches the sensor it starts a chain of activity through-out the sensors internal components, which in turn sends a signal tothe circuit board inside the housing. A red LED is illuminated how-ever if there is a sensor failure or other component failure, the relaywill immediately transfer to the alarm condition.

InstallationThe 688 mounts in many positions.

ApplicationThe Model 710 Series are float-operated units designed for exter-nal mounting to the process vessel and provide high pressure capa-bilities with low specific gravity ratings within the petroleum,power and natural gas industries. These models provide reliablemagnetic switching for level alarm or control function applications.

Features• Construction Versatility: Standard Level Control includes a Carbon

Steel float cage with a choice of threaded, socket-weld orflanged tank connection. Consult factory for other materials.

• Explosion Proof: CSA APPROVEDClass I, Division I, Groups C & DClass II, Groups E, F & GClass III, Enclosure Type 4

• Various Models: A wide selection of cage & trim materials andswitch mechanisms are available.

• 100% Hydrostatic Test @11/2 Times Related Pressure.

Operation As the liquid rises, the float moves the attached magnetic attractionsleeve into the field of the magnet located in the switch housing. Asthis magnet swings toward the enclosing tube, it causes themicroswitch to actuate. As the liquid level falls, the magneticattraction sleeve moves out of the magnetic field and the biasspring pulls the magnet away from the enclosing tube, which deac-tuates the micro switch.

740 Top Mount Displacer ControlApplicationThe Model 740 Series are displacer-operated units designed forinternal mounting through the top of the process vessel and providehigh pressure capabilities with low specific gravity ratings withinthe petroleum, power and natural gas industries. The use of dis-placers allows for a narrow or wide-switching differential, fieldadjustable switch points, high pressure applications and multipleswitching points by means of dual switching mechanisms.

Features• Construction Versatility: Standard Level Control includes Stainless

Steel Displacer and Carbon Steel NPT or flanged tank connections.Consult factory for other materials.


• Various Models: A wide selection of connection, trim materialsand switch mechanisms are available.

Operation The stainless steel float/displacer, which is heavier than the liquid,is suspended by a spring. When liquid rises around the displacer, abuoyancy force is produced, which causes the effective weight ofthe displacer to change. This causes the spring to retract slightly toa new equilibrium position. When the spring retracts, the attractionsleeve also moves upward into the field of the external magnet. Themagnet moves forward toward the attraction sleeve that actuatesthe micro switch.

Displacer Advantages As the liquid level rises, the buoyancy force produced by the dis-placer causes the range spring to seek a new balance.1. Ability to withstand higher pressure than a float, since displacers

can be solid or constructed with a much heavier wall.2. Allows wide switching differentials.3. Allows switch point to be adjusted by moving the displacer up

or down.

Snap-Acting Pilot • No-Bleed Positive On/Off Flow ActionThe Snap-Acting Pilot is comprised of two inner valves. Valve (1) admits system sup-ply gas to output. Valve (2) controls system exhaust from output. Valve (1), as shownin the closed position (Fig. 1), is held closed by force exerted from supply gas. Whenupward flapper bar force transferred to Valve (2) is sufficient enough to overcomesupply force, the ball snaps upward, allowing supply pressure to output port, whichoperates the diaphragm motore valve (not shown nor included with the control). Thespherical end of valve (2) closes the exhaust port the instant the ball snaps upwardand remains seated against supply pressure until force on the valve diminishes. Asforce is removed from valve (2), causing it to unseat, a simultaneous action occurs,causing valve (1) to seat instantly, closing the supply port to output and opening out-put to exhaust, allowing the diaphragm motor valve to reverse it’s action.

Throttle Pilot • No-Bleed Modulating Flow ActionThe Throttle Pilot utilizes a diaphragm, which creates a forced balance pilot (Fig 2).Output pressure acts upon the diaphragm causing it to push back at the same forcebeing applied to the lower seat. More force on the seat produces a proportionateincrease in pilot pressure. When the flapper bar of the control exerts upward force onthe lower valve seat (3), it forces the lower seat closed against valve body and opensthe supply valve (4). (Supply pressure enters the system, increasing until the controland diaphragm motor valve pressure equals the flapper bar force and produces a forcedsystem balance.) The control will stay in this position until a decrease in the tank levelreduces the force allowing exhaust, or an increase in the level produces an action asdescribed. System supply gas does not flow while the pilot is in balance.

*Displacer Arm Length: Arm length is figured from center line of control box. 15"Standard on vertical displacer, 12 1/2" Standard on horizontal displacer. (Otherlengths available upon application)

7400 Snaptrol Pneumatic & Electric Liquid Level Control, Low Pressure No-Bleed

ApplicationFor use in low-pressure vessels or tanks, this versatile and multi-optional device can be used as a level control or as a component ofHi-Lo level alarm systems. The 1" MNPT unit may be mounted intoa 1" coupling when the float is accessible from inside the vessel. Iffloat is not accessible, a 2" or larger connection must be provided toallow passage of the float through the connection. The pneumatic 3-way 2-port no-bleed pilot valve makes this unit an excellent choicefor the control of liquid level in oil and gas production equipment suchas separators, dehydrators, treaters, as well as in manufacturingplants, hazardous waste disposal, food processing, petro-chemicalfacilities, or wherever fluid levels need to be monitored or controlled.

1800 Pneumatic & Electric Liquid Level Control, Low Pressure No-Bleed

ApplicationThe WellMark 1800 Liquid Level Control offers design simplicity,easy installation, adjustment, and reliable liquid-level monitoring.The Model 1800 can be equipped with a snap action 3-way 2-portvalve (1800M) or an electrical contact switch (1800E).The Model 1800 is actuated by movable arms that permit the con-trol range to be adjusted easily and accurately set to the rangedesired. With the liquid level below the float, the 3-way 2-portvalve, or micro switch, will be in low level position and will remainthere until the float rises to the pre-set high level. The 3-way 2-portvalve, or micro switch, reverses positions as the float rises or dropsthrough the pre-set level.The 1800 Liquid Level Control can be used in oil and gas process-ing, manufacturing plants, hazardous waste disposal, food process-ing, petro-chemical facilities, or wherever fluid levels need to bemonitored or controlled.

Installation The WellMark Model 1800 is available with various standard pipeclosures such as ANSI flanges and grooved connections.

Snap Action Throttling

ApplicationThe Cantilever liquid level control series offers design simplicity,easy installation, adjustment, and reliable liquid level monitoring. Itis a highly efficient device for the control of liquid level in oil andgas production equipment such as: separators, dehydrators, andtreaters, as well as in manufacturing plants, hazardous waste dis-posal, food processing, water treatment, petro-chemical facilities, orwherever fluid levels need to be monitored or controlled. The sens-ing element design, with no moving parts exposed to the tank orvessel fluid, makes the simple installation of the control possible invarious standard pipe closures such as: ANSI flanges and grooved,or union, connections. The sensing element has a selection of threecontrol head options that control pneumatic supply to controlvalves, alarm systems, pressure switches, solenoids, and relays, allof which may be used in response to liquid level changes. Thesecontrol options are:

ThrottlingThis throttling control head assembly provides a proportional outputpressure signal as changes in vessel liquid levels are sensed by thedisplacers and transmitted by the sensing rod. Constant vessel liq-uid level can be maintained when the control outlet is connectedwith a properly sized pneumatic, diaphragm activated control valve.Sensing adjustment is controlled by an external adjusting screw.

Snap ActionThe snap action control head assembly provides on/off supply pressure at a specific liquid level set point established by the displac-er setting. This on/off signal can be used to power pressure switch-es, start-up or shut-down controls, alarms, or pneumatic diaphragmactivated control valves to open or close system flow lines.

6900Section No. 3.5

6900 Cantilever Liquid Level Control Principle of OperationThis liquid level control operates on the basis of two basic phys-ical laws:

1. “A solid, heavier than a fluid (a displacer/s) will, if placed in it,descend to the bottom of the fluid, and the solid will, whenweighed in the fluid, be lighter than its true weight by the weightof the fluid displaced.”–Archimedes' Principal

2. A Cantilever beam (sensing rod) projecting outward, anchored atone end, will flex in proportion to the weight applied, or removed,at the free end.

Therefore, following Archimedes' Principal, a body (displacer orfloat) immersed in a fluid experiences a buoyant, or lift force equalto the weight of the displaced fluid. This static lift force acts verti-cally through the center of gravity of the displaced volume.

Applying the above fundamentals to this liquid level control, we cansense and regulate levels of most gas to fluid interface applicationsas well as many fluid to fluid interfaces.

By attaching a displacer to the free end of the sensing rod, verti-cal movement is achieved. The rising and lowering of the fluidgives the static lift force-either up or down, which is transferredalong the rod to an actuator pad extending out past the anchoredend. As the actuator pad moves to the nozzle, supply pressure isdiverted to output, opening a diaphragm-operated motor valve. Asfluid is drained, and fluid level declines, the actuator pad movesaway from the nozzle and supply pressure is relieved from thediaphragm operated motor valve, and valve closes, allowing thecycle to repeat.

In a throttling mode, this procedure will continually throttle thevalve to maintain the fluid level at a desired set point.

In a snap-acting mode, a shuttle pilot is attached to the throttlinghead converting the throttling output pressure to pilot signalpressure, tripping the shuttle pilot to either full supply pressure,opening valve quickly, or to zero supply pressure, allowing valveto close.

InstallationBefore installing this control, inspect the unit for any shipment dam-age or any foreign material. Visually observe that the actuator padand rod-end are centered in the sensing rod connector. If not, theunit has been distorted and should be returned to center beforeplacing the control in service.

Check for mechanical clearance of displacer for free movement byflicking the actuator pad after installation of the unit. If vibration isobserved, unit is free to work as intended.

Connect suitable supply gas line to the 1/4" FNPT connectionstamped "IN". 20 to 30 psi is recommended for proper operation(Filtered gas or air is strongly recommended for better and longermaintenance-free operation.)

Connect "output" port, stamped "OUT" to unit to be controlled.

Start-Up ProcedureEnergize the control by opening the supply gas to pilot head (20 to30 psi recommended).

Adjust the nozzle upward toward the actuator pad, by looseningnozzle lock nut and turning nozzle clockwise, until output pressuregauge starts to indicate a reading (1-3 psi).

Observing the fluid level through the level glasses for desired level,adjust the nozzle up or down to actuate the diaphragm-operatedmotor valve when desired level is obtained. When satisfactory fluidlevel is obtained, tighten nozzle lock nut to secure setting.

Observe several cycles to assure that the system is properly func-tioning.

NOTE: To increase fluid level set-point, adjust the nozzle counter-clockwise away from the actuator pad. To decrease fluid level set-point, adjust nozzle counter-clockwise toward actuator pad.

Normal pilot installation is direct acting, rise in fluid level resultingin an increase of output. For indirect acting, rise in fluid level result-ing in a decrease of output, simply loosen 3/4 -16 jam nut behindpilot head, and rotate pilot head 180˚ and retighten 3/4 -16 jam nut.

PT988 Pneumatic Liquid Level SwitchApplicationWellMark’s PT988 Pneumatic Level Switch is designed for horizon-tal mounting in a tank or vessel through threaded or flanged pipeconnections (will work in an API 2" full coupling) and is excellentfor applications where space is a factor. It can be externally cagedfor vessel isolation and can be used as a high or low level alarm,as well as a liquid level control. In addition, it can be switched fromdirect to indirect action simply by inverting the unit 180˚.The PT988 features a 3-way snap-acting pilot (0 to full outputusing 20-30 psi supply pressure) or order it with an optional throt-tling pilot (3 to 15 psi output with a 20 psi supply pressure).

OperationAs liquid within the vessel varies, linear movement of the float isconverted to rotary movement of the actuator assembly. In the snapacting mode, as the actuator pad moves closer to the nozzle, supplypressure is diverted to signal pressure, tripping the shuttle pilot toeither full output pressure, energizing end-device, or to zero outputpressure, de-energizing end-device. In the throttling mode, as theactuator pad moves closer to the nozzle, supply pressure is diverted tooutput pressure, resulting in modulating pressure to the end-device.Direct ActingA rise in fluid level resulting in an increase of pilot output. This isaccomplished when the pilot is in the downward positionIndirect ActingA rise in fluid level resulting in a decrease of pilot output. This isaccomplished when the pilot is in the upward position.

9321/9321E Pneumatic & Electric Liquid Level Switch

ApplicationThe WellMark Series 9321 On-Off Pneumatic Liquid Level Switchoperates shut-down valves or alarm systems when liquid in a ves-sel reaches a predetermined level. This switch uses an externallymounted displacer that operates a nozzle-flapper to vent the supplypressure when the switch is activated. The nozzle-flapper has a softseat for tight shut-off when the switch is in its normal position(flapper against the nozzle).

The Series 9321E is an external cage-mounted electric liquid levelswitch. Rising liquid exerts a buoyant force on the displacer, pro-ducing a torque in the tube. This force will either trip or reset anelectrical switch. Falling liquid will trip or reset the same switch ifso desired. The WellMark Series 9321E Electric Switch uses thedisplacer and torque tube movement to trip and reset an electricswitch for on-off condition. The displacer can withstand up to 11/2times the maximum working pressure, allowing it to remain in thecage during hydrostatic testing.

Features• Pneumatic or Electric

• Left Hand or Right Hand

• Hi-Level Alarm or Lo-Level Alarm

SpecificationsOutput Signal:Pneumatic Output equal to supply pressure when the switch is inthe normal position. Output reduced to approximately atmosphericpressure, depending upon size of the bleed orifice and piping con-figuration, when the switch is activated. Electric output same assupply signal.

9321Section No. 3.7

9321/9321E Pneumatic & Electric Liquid Level SwitchPrinciple of OperationThe Series 9321 (Figure 1) is an external, cage-mounted pneumat-ic liquid level switch. When the switch is in the normal positionwith the flapper against the nozzle, output pressure cannot bleed offand remains the same as full supply pressure. Rising liquid levelexerts a buoyant force on the displacer, producing a torque in thetube. When this torque exceeds the torque exerted on the flapper bythe magnet, the flapper snaps away from the nozzle. This actionallows output pressure to bleed through the nozzle faster than supplypressure can enter through the bleed orifice. The reduced pressure

in the output signal line activates the shutdown or alarm systemsWhen the liquid level lowers, the falling displacer forces the flapperinto the field of the magnet, letting the magnet snap the flapperagainst the nozzle and causing output pressure to build to full sup-ply pressure.On applications where low-level switch operation is required(Figure 2) the nozzle, flapper and magnet are positioned on theopposite side of the torque tube so that downward displacer travelmoves the flapper away from the nozzle.

MIZER® No-Bleed Pilot ValveApplicationThe MIZER® No-Bleed Pilot Valve is the most cost-effective solu-tion for converting high-bleed pneumatic controls to low-bleedoperation. This device effectively stops continuous bleed operationbetween dump cycles, thereby reducing environmentally-concern-ing methane emissions, while allowing previously wasted gas to besent to the sale line. Conservatively, user can anticipate 90% sav-ings from recaptured gas based upon estimated cycle rates of thecontrols. 95-98% values may be achieved in some applications.

Features• Kits Available For:

• Cemco Cantilever Level Controls• FMC Invalco Flexlever Level Controls• Emerson/Fisher 2500 Level Controls• Emerson/Fisher 4100Z "Wizard" Pressure Controllers• Emerson/Fisher 4150/4160 Pressure Controllers

• Cemco and FMC Invalco kits are field-installable in minutes – unit does not have to be shut down for installation. Installation of pressure controller kits, although more in-depth, are still the most painless and cost-effective solution for converting high-bleed to low-bleed.

• Uses existing tubing and connections – no new plumbing required.

• MIZER® works in either snap acting or throttling application.• MIZER® solution allows field personnel to continue using

control devices that are familiar.• Conversion from high-bleed to low-bleed may qualify user

for Carbon Credits.

Bleed Gas vs. Vent Gas"Bleed" gas is defined as gas that bleeds to atmosphere betweendump cycles. "Vent" gas is that gas which, after energizing the dumpor control valve must be released to atmosphere, and is usually asmall fraction by comparison to the bleed gas volume. It is becauseof the high bleed between dump cycles that the EPA discourages theuse of high-bleed pneumatic devices to control liquid level and gaspressure. The MIZER® device actually stops the continuous flow ofgas from these controllers, only allowing gas to flow to the con-

MIZER®

trolled device (dump valve or control valve)when necessary. Therefore, the amount ofpotential gas savings is dependent upon(among other things) the initial bleed rateand the frequency of operation of the con-troller and valve. In other words, a separatorunit that fills slowly and dumps infrequentlyis bleeding substantial amounts of unutilizedgas pressure to atmosphere most of thetime. All of this gas that is vented toatmosphere between dump cycles wouldbe saved when using a MIZER® retrofit-ted controller. Likewise, if the controlleris very active, dumping fluid frequently,the savings would be less, as more gasis being used to activate the valve.It should be noted that neitherthe MIZER® nor any other low-bleed device is capable of sav-ing gas that has been used toenergize the valve. This gaswill always be lost after thevalve cycles and the diaphragm andconnection lines vent. If the lines are not allowed to vent the valvewill not return to the original (usually closed) position.

Ease of InstallationThe Cemco and FMC Invalco level control versions of the MIZER®

pilot valve installation is a simple and painless operation. In fact,unlike installing traditional no-bleed level controllers, which requirebreaking the process connection, the MIZER® pilot valve is installedby simply removing the operating gas pressure from the controller,installing the MIZER®, blowing out the supply line to keep it clean,reattaching the supply line and adjusting.Different controllers require different kits–some containing moreparts than others. Retrofit kits for pressure controllers such as theEmerson/Fisher 4150 or 4160 are more complex and therefore theprocedure is also more complex, possibly requiring shut down. But,no welding of new fittings, no new tubing, no new cabinet refits arerequired. The MIZER® installs in minutes – not hours or days as isthe case with installation of any complete new controller. Last, butnot least, the operator continues using the controller they alreadyknow and trust – no need to learn the operating quirks of a com-pletely new control.

When the MIZER® Pilot Valve is in “SteadyState”, both Seal “A” and Seal “B” are closedand the Control Flapper is in neutral position.(See Fig. 1)

Depressed Position: (Non-Venting Actuating)When the Control Flapper depresses theActuation Poppet, Seal “A” is opened, supply-ing gas to the process valve. Seal “B” isclosed, preventing gas from bleeding or vent-ing through the vent port. The MIZER® PilotValve is designed so that the gas flow isrelated to the position of the controller flap-per. (See Fig. 2)

Released Position: (Non-Continuous Venting)When the Control Flapper is released it clos-es Seal “A” and opens Seal “B” allowing gasto vent. Venting occurs ONLY when the controlvalve calls for it, and then, ONLY the gas inthe process line and actuator is released. (See Fig. 3)

W7702 Back Pressure Regulator (BPR)

ApplicationThe WellMark Back Pressure Regulator is an excellent and eco-nomical device for automatic relief of pressure in liquid service. It isactuated by the static upstream pressure, which causes the valve toopen at set pressures. The degree of opening will vary and increasein proportion to the increase in pressure over the opening pressure.

The WellMark Back Pressure Regulator is offered in a 2” size. The2” is suitable for pressure settings up to 1500 psi.

Recommended for a variety of oil and gas production applications,including the following:

Paraffin:A common cause of paraffin build-up is gas breaking out of solu-

tion in the tubing string. Through use of this regulator, constantpressure can be maintained on the oil column, permitting gas bub-bles to be pumped out of the string before they rupture and breakout of solution.

Heading up:This regulator, installed on wells that tend to head up and flow, willassure a full tubing string by maintaining constant pressure on theoil column. This assures continuous lubrication of the polish rod,adding to the life of the stuffing box rubbers. This also enhancesefficiency of the bottom hole pump.

By-Pass to Casing:This regulator can also be used as a by-pass to the casing in eventlead lines should freeze or get plugged.

Other Uses:For LACT units to assure full-line operation and for safety relief onseparators or casing.

Overpressure Protection As is true with most regulators, the WellMark “Top Gun” Series 2001PRRegulator has an outlet pressure rating that is lower than the inletpressure rating. Overpressure protection is needed to avoid overpres-sure if the actual inlet pressure can exceed the outlet pressure rating.

Dimensional Data

1. The sum of the outlet pressure setting and the maximum allow-able pressure drop determines the maximum allowable inletpressure for a given installation. For example, with a 3/8" seatring orifice (maximum pressure drop of 500 psi) and a 275 psigoutlet pressure setting, the maximum inlet pressure is 775 psig(500 psi + 275 psig).

1. Internal parts of the regulator may be damaged if the outlet pres-sure exceeds the pressure setting beyond the amounts shown.

2. This applies to outlet pressure settings below 350 psig only. Forpressure settings above 350 psig, outlet pressure is limited to550 psig, the maximum emergency outlet (casing) pressure.

1. Capacity is based on 20% droop unless otherwise noted. See “Capacity Data”for equivalent capacities of other gases.

2. For pressure settings under 10 psig, inlet pressure should be limited to approx-imately 100 psig so the set point adjustment can be reached.

3. For pressure set point of 5 psig, the droop is 2 psig.

Capacity DataNatural gas regulating capacities for selected inlet pressures and out-let pressure settings are shown in Table 2. Flows are in scfh (60˚Fand 14.7 psia) of 0.6 specific gravity, natural gas at 60˚F. To deter-mine the equivalent capacities for other gases, multiply the tablecapacity by the following factors: for air use 0.775, for nitrogen use0.789, for propane use 0.628, or for butane use 0.548. For gases ofother specific gravities, multiply the given capacity by 0.775, anddivide by the square root of the particular specific gravity.

EIP Solar-Powered Chemical Injection Pump with DigiMax ADC ControlApplicationThe WellMark EIP Solar-Electric Chemical Injection Pump providesan environmentally-clean method for injection of chemical into aline under pressure. It is a positive-displacement design, poweredby an electric motor, thereby eliminating the gas emissions inherentwith pneumatic-style pumps. Applications include injection ofmethanol, corrosion inhibitors, friction reducers or scale inhibitorsinto wellheads or pipelines. Unique Temperature Sensor allowsoperator to set temperature threshold to disallow pumping untiltemperature falls to a specified level.

Principle of OperationAny chemical injection pump utilizing a photovoltaic power systemmust manage numerous variables in an attempt to maintain ade-quate power for the task at hand. Among those variables are:• Available Sunlight• Size and Capability of the Solar Panel• Size of the Battery or Batteries• Power Draw of the Motor• Size/Displacement of the Plunger• Required Discharge Pressure of the Pump

All of these variables must be considered when sizing a photo-voltaic pump system.

Unit Positioning and Panel Tilt AdjustmentRegional information about available sunlight can be found athttp://www.nrel.gov/gis/solar.html. Further evaluation of the spe-cific site may be necessary to maximize clear presentation of thesolar panel to the sun. Any adjacent items that may casts shadowson the panel throughout the day will negatively affect the overallperformance of the package. Maximum exposure will help to assurethat the battery maintains enough power to drive the pump through-out the night.To get the most from position-fixed (or seasonally adjusted) photo-voltaic solar panels, you need to point them in the direction thatcaptures the most sun.Solar panels should always face true south in the NorthernHemisphere, north in the Southern Hemisphere, tilted from the hor-izontal at a degree equal to your latitude plus 15 degrees in winter,or minus 15 degrees in summer.An additional 3- 5% can be gained by evaluating this more care-fully and fine-tuning adjustments accordingly.

EIP Solar-Powered Chemical Injection Pump with DigiMax ADC Control

Temperature SensorThe Control Timer is equipped with a Temperature Sensor feature.When activated this feature turns the pump off until the temperaturedrops to a set temperature threshold or lower, regardless of programsettings. This allows the user to minimize the waste of methanol byonly pumping during conditions approaching freezing temperatures.

settings. Control of fluid volume can be achieved by utilizing aninfinite number of combinations of RUN and OFF times along withthree different displacement settings. Suggested settings for commonvolumes are listed on included charts.

Program FunctionsAuto ModeAfter a one-time setup, this feature allows the operator to simplyenter the number of quarts desired per day - No need to consult RUNTIME and OFF TIME charts. The DigiMax ADC is programmed to behassle-free. Of course, Manual Mode is available allowing the userto manually set the control if desired.In Auto Mode Digital Display continuously indicates settings:• Plunger Size and Pin Setting• Battery Voltage• Temp. Settings (ON/OFF, Temp. Threshold Setting and Current)• Pump Rate (Quarts per Day)

In Manual Mode Digital Display continuously indicates settings:• RUN Time• OFF Time• Cycle Count• Battery Voltage• Temp. Settings (ON/OFF, Temp. Threshold Setting and Current)

Pump OverrideRuns pump continuously, overriding the program until the button ispressed again or until the pump runs for 5 minutes.

Pump SelectionA wide ratio between OFF time and RUN time (OFF:RUN) will usual-ly result in maximized efficiency of the battery/solar charging system.For example: 30 seconds OFF time versus 5 seconds RUN timewould result in a ratio of 6:1. Ratios lower than 2:1 may result inprogressive loss of battery charge, depending upon available sun-light and differential pumping pressure.As reviewed against the “Pump Displacement & Timer Settings”charts, (refer to Installation, Operation & Maintenance Instructionsfor Solar-Powered Chemical Injection Pump) the pump's requiredrate should optimally fall within the middle of the pumps capacityrange. This gives room for adjustment if the service criteria changes.

OperationThe WellMark Solar Electric Chemical Injection Pump features acontrol timer that allows a broad range of operating conditions.The pump head can be adjusted for one of three different displacement

Pin position (1, 2 or 3) determines displacement (see charts).Factory preset is Position 3.

EIPSection No. 6.3

EIP AC-Powered Electric Chemical Injection Pump with DigiMax ADC ControlApplicationThe WellMark EIP AC-Powered Electric Chemical Injection Pumpprovides an environmentally-clean method for injection of chemicalinto a line under pressure when AC power is available. It is a posi-tive-displacement design, powered by an electric motor, therebyeliminating the gas emissions inherent with pneumatic-stylepumps. Applications include injection of methanol, corrosioninhibitors, friction reducers or scale inhibitors into wellheads orpipelines. Unique Temperature Sensor allows operator to set tem-perature threshold to disallow pumping until temperature falls to aspecified level.

EIPSection No. 6.3

EIP AC-Powered Electric Chemical Injection Pump with DigiMax ADC ControlOperationThe WellMark AC-Powered Electric Chemical Injection Pump featuresa control timer that allows a broad range of operating conditions.The pump head can be adjusted for one of three different displace-ment settings. Control of fluid volume can be achieved by utilizingan infinite number of combinations of RUN and OFF times alongwith three different displacement settings. Suggested settings forcommon volumes are listed on charts included with each pump.As reviewed against the “Pump Displacement & Timer Settings”charts, (refer to Installation, Operation & Maintenance Instructionsfor Solar-Powered Chemical Injection Pump) the pump's requiredrate should optimally fall within the middle of the pumps capacityrange. This gives room for adjustment if the service criteria changes.

Temperature SensorThe Control Timer is equipped with a Temperature Sensor fea-ture. When activated this feature turns the pump off until thetemperature drops to a set temperature threshold or lower,regardless of program settings. This allows the user to minimizethe waste of methanol by only pumping during conditionsapproaching freezing temperatures.

Program FunctionsAuto ModeAfter a one-time setup, this feature allows the operator to simplyenter the number of quarts desired per day - No need to consult RUNTIME and OFF TIME charts. The DigiMax ADC is programmed to behassle-free. Of course, Manual Mode is available allowing the userto manually set the control if desired.

In Auto Mode Digital Display continuously indicates settings:• Plunger Size and Pin Setting• Temp. Settings (ON/OFF, Temp. Threshold Setting and Current)• Pump Rate (Quarts per Day)

In Manual Mode Digital Display continuously indicates settings:• RUN Time• OFF Time• Cycle Count• Temp. Settings (ON/OFF, Temp. Threshold Setting and Current)

Pump OverrideRuns pump continuously, overriding the program until the button ispressed again or until the pump runs for 5 minutes.

Pin position (1, 2 or 3) determines displacement (see charts).Factory preset is Position 3.

ApplicationThe Series W2012 Pilot can be used with both Back PressureValves and Pressure Reducing Valves. The Pilot will control pressure on scrubbers, separators and other liquid accumulatorswhere the pressure must be maintained at a constant level. When used with Model 4050V (or any other motor valve), the W2012 Pilot can be used to maintain a constant field adjustable pressure setting.

OperationSignal Pressure is introduced to this simple and near-balaced double diaphragm design. With the upper diaphragm arrangementbeing a bit larger than the lower diaphragm arrangement, the signalpressure when applied moves the diaphragm assembly upward.Variable spring tension opposes this movement which can be adjusted to the desired set pressure.

The diaphragm assembly moves upward when the signal pressureis such as to overcome the adjusted spring tension. This closes supply to output and opens output to exhaust. The reverse occurs asthe signal pressure decreases. The diaphragm assembly moves downward closing exhaust from output and opening supply to output. This action creates a throttling movement which maintainsthe desired output for the pressure setting. Output from 0 to full supply pressure is proportional to signal pressure.

3535 Back Pressure Valve, Low Pressure, Single Seat

ApplicationWellMark’s Back Pressure Valve can be used in any installationwhere upstream pressure is required to be kept at a preset range.It may also be used as: a pressure relief valve, a custody transferdump valve to hold a certain back pressure, or as a separator backpressure valve on the gas or liquid side. Upstream pressure isapplied to the bottom of the diaphragm through connecting tubing.Spring tension above the diaphragm opposes this pressure, andwhen the pressure exceeds the pressure setting on the spring, theplug is raised off the seat. By varying the spring tension, the pres-sure setting can be varied.The typical application for these valves is to hold back pressure onseparators, treaters, Lact units, etc.

Features• Simple Design• Self-Contained:There are no pilots or small orifices to plug or freeze.• Easy Access: All internal parts can be removed without taking

5555 Back Pressure Valve, Double Seated (Balanced)ApplicationThis unique valve, with its simple and near-balanced double-seat-ed design, along with its history of trouble free operation, has con-tributed materially to its wide acceptance in the oil industry.Primary application is to hold back pressure on separators, treaters,Lact units, and other accumulators when upstream pressure isrequired to be kept at a preset range. However, this valve may alsobe used as a differential valve by utilizing secondary signal pres-sure, along with spring force on top of the diaphragm, to opposeflow pressure applied to the bottom of the diaphragm.

Features• Simple Design

• Self-Contained:There are no pilots or small orifices to plug or freeze.

• Easy Access: All internal parts can be removed without takingvalve out of line.

• Available in 2" Threaded: 2", 3", 4" Flanged

• Molded Buna-N or Viton® Plugs for Corrosion Resistance &Tight Shut-Off

2021 Flow Control Throttling Valve

ApplicationThe WellMark Throttling Valve is designed to function as a pressurecontrol valve, and will handle pressure drops up to 4500 psi liquidand 2200 psi gas. It has been used widely in gas gathering systemsto regulate flow, CO2, and steam injection systems, as well as inlow, medium, and high-pressure separators.

Features• Anti-Cavitating Plug Design

• Manual or Electric Actuation

• "Y" or Angle Style Body: Carbon or Stainless Steel

• Multiple Orifice Sizes

• Low Torque at High Differential Pressure

• Wide Cv Range: 3.2 - 95

OperationMost control valves operate similar to the nozzle on a garden hose.When the valve is set to a partially closed or choked position, theflow of fluid decreases in pressure and in turn increases in veloc-ity. This high velocity stream causes two problems: mechanicalerosion or wear and a highly destructive process called cavitation.After sustained use, these processes will result in premature valvefailure.

The 2021 Series' unique throttling choke valve design remediesthese self-destructive processes by channeling the fluid into acylinder through opposing slots in its sides; thus, allowing eachmini-stream to impinge on itself, changing the otherwise high-velocity laminar flow into a disrupted non-linear stream, eliminat-ing the destructive effects of erosion and cavitation. The plug alsoprovides extraordinary accurate control to less than 0.1%. Theresult is long valve life and highly reliable precision control.
