Both flow conduits are designed to ensure laminar flowsand therefore the ratio of their flow rates is constant. Twoprecision temperature sensing windings on the sensortube are heated, and when flow takes place, gas carriesheat from the upstream to the downstream windings.The resultant temperature differential is proportional tothe change in resistance of the sensor windings.

A Wheatstone bridge design is used to monitor the tem-perature dependent resistance gradient on the sensorwindings which is linearly proportional to the instanta-neous rate of flow.

Output signals of 0 to 5Vdc and 4 to 20mA are generat-ed indicating mass molecular based flow rates of themetered gas.

Flow rates are unaffected by temperature and pressurevariations within stated limitations.

General Description

Compact, self contained GFM mass flow meters aredesigned to read flow rates of gases. The rugged designcoupled with instrumentation grade accuracy providesversatile and economical means of flow control.

Aluminum or stainless steel models with readout optionsof either engineering units (standard) or 0 to 100 percentdisplays are available.

The mechanical layout of the design includes an LCDreadout built into the top of the transducer. This readoutmodule is tiltable over 90 degrees to provide optimalreading comfort. It is connected to the transducer by astandard modular plug, and is also readily removable forremote reading installations. Transducers without LCDreadout are offered for OEM applications.

GFM mass flow meters are available with flow rangesfrom 10 sccm to 1000 sL/min N2. Gases are connected

by means of 1/4” 3/8” 1/2” compression fittings and 3/4”FNPT fittings. Optional fittings are available. These

controllers may be used as bench top units or mountedby means of screws in the base.

Transducer power supply ports are fuse and polarityprotected.

Low Cost Mass Flow Controllers

Model GFC thermal Mass Flow Controllers aredesigned to indicate and control set flow rates of gases.

The GFC combines the characteristics, and accuracyof conventional mass flow devices into a unique com-pact design at low costs previously unattainable.

Each of these controllers incorporates an advancedstraight tube sensor in conjunction with flow passageelements constructed of aluminum and brass fornon-corrosive gases or 316 stainless steel for corrosiveapplications. Zero and span adjustments are accessi-ble from the outside of transmitters.

Principles of Operation

Metered gases are divided into two laminar flow paths,one through the primary flow conduit, and the otherthrough a capillary sensor tube.

Design Features

Rigid metallic construction.Maximum pressure of 1000 psig (70 bars).Leak integrity 1 x 10-7 smL/sec of helium.NIST traceable certification.Built-in tiltable LCD readout.Local or remote setpoint control.0-5 Vdc and 4-20 mA signals.Circuit protection.Totalizer option.

Both flow conduits are designed to ensure laminar flowsand therefore the ratio of their flow rates is constant.

Two precision temperature sensing windings on the sen-sor tube are heated, and when flow takes place, gas car-ries heat from the upstream to the downstream windings.The resultant temperature differential is proportional tothe change in resistance of the sensor windings.


Output signals of 0 to 5Vdc and 4 to 20mA are generat-ed indicating mass molecular based flow rates of themetered gas.

The combined gas streams flow through a proportionat-ing electromagnetic valve with an appropriately selectedorifice. The closed loop control circuit continuously moni-tors the mass flow output and maintains it at the set flowrate.

Flow rates are unaffected by temperature and pressurevariations within stated limitations.

General Description

Compact, self contained GFC mass flow con-trollers are designed to indicate and control flowrates of gases. The rugged design coupled withinstrumentation grade accuracy provides versatile

and economical means of flow control. Aluminum orstainless steel models with readout options of either engi-neering units (standard) or 0 to 100 percent displays areavailable.

Totalizer

Totalizer

This compact totalizer is designed to be used pri-marily with mass flow meters and mass flow con-trollers. It can also be used in conjunction withother types of instrumentation with 0-5 Vdc sig-nal outputs.

The totalizer takes analog output flow signals ofeither 5 to 10 Vdc, from GFM mass flow metersand GFC mass flow controllers, or 0 to 5 Vdcfrom AFC mass flow controllers, AFM mass flowmeters and other compatible products (jumperselectable).

The totalizer integrates and accumulates up to 7digits of direct engineering units for the given gasand flow rate (i.e. standard liters, standard cubiccentimeters, etc.).

In order to reduce low signal (noise) totalizing,provision is made for 1% cut off.

A built-in battery back-up holds the total readingfor up to 20 years.

The totalizer can be connected to GFM massflow meters or GFC mass flow controllers viaeither a modular jack replacing the LCD displayor with an additional connector in parallel withthe LCD display.

Each totalizer is shipped from the factory withadjustments made for specified flow rates. Thetotalizer can be re-scaled for a different flowrange or engineering unit.

Principles of OperationMetered gases are divided into two laminar flow paths,one through the primary flow conduit, and the otherthrough a capillary sensor tube. Both flow conduits aredesigned to ensure laminar flows and therefore the ratioof their flow rates is constant. Two precision tempera-ture sensing windings on the sensor tube are heated,and when flow takes place, gas carries heat from theupstream to the downstream windings. The resultanttemperature differential is proportional to the change inresistance of the sensor windings.

A Wheatstone bridge design is used to monitor the tem-perature dependent resistance gradient on the sensorwindings which is linearly proportional to the instanta-neous rate of flow. The output of the Wheatstone bridgeis converted to digital format with a 12 Bit ADC (analogto digital converter).

An on-board microprocessor and non-volatilememory store all calibration factors and directly

control a proportionating electromagnetic valve. Thedigital closed loop control system continuously com-pares the mass flow output with the selected flow rate.Deviations from the set point are corrected by compen-sating valve adjustments, with PID algorithm thus main-taining the desired flow parameters with a high degreeof accuracy. Output signals of 0 to 5Vdc or 4 to 20mAare generated indicating mass molecular based flowrates of the metered gas.

Microprocessor driven digital flow controllers allow oneto program, record, and analyze flow rates of variousgases with a computer via an RS-485 interface (optionalRS-232 is available).

Conversion Factors

Conversion factors for up to 256 gases are stored in the DFC.Conversion factors may be applied to any of the ten gas calibrations viadigital interface commands.

Flow Alarms

High and Low gas flow ALARM limits are programmed using the digitalinterface. Alarm conditions are reported via the digital interface or canactivate the contact closure outputs.

Programmable Flow

Aalborg software supports programmable flow modes, allowing execu-tion of custom programming of up to ten steps.

Various flow configurations include ramping, linearized increasing anddecreasing modes.

Auto Tune

The AUTO TUNE function allows the DFC to automatically optimize con-trol response for the gas under actual process conditions.

During the AUTO TUNE process, the instrument adjusts PID gains foroptimum step response and determine key control valve characteristics(only available on units with less than 80 L/min maximum flow).

Interface

The digital interface operates viaRS485 (optional RS232) and providesaccess to applicable internal dataincluding FLOW SET POINT, ACTUALFLOW, ZERO ADJUSTMENTS, andLINEARIZATION TABLE ADJUST-MENTS.

The analog interface provides 0 to5Vdc, 0 to 10Vdc and 4 to 20 mAinputs and outputs.

Auto Zero

The DFC automatically nulls the sen-sor zero offset whenever the flow setpoint is below 2% of full scale.

To accommodate this feature the con-trol valve must fully close under thatcondition. Provisions are made toeither disable, force or store the cur-rent auto zero via digital commands.

Totalizer

The firmware for the DFC providesfunctions to register total gas quantity.The total mass of gas is calculated byintegrating the actual gas flow rate withrespect to time.

Digital interface commands are provided to:

SET the totalizer to ZERO.START /STOP totalizing the flow.READ the totalizer.START the totalizer at a preset flow.STOP the flow at a preset total.

Multi-Gas Calibration

The DFC is capable of storing primarycalibration data for up to 10 gases.Thisfeature allows the same DFC to be cal-ibrated for multiple gases while main-taining the rated accuracy on each.

Model AF mass flow meters and controllers aredesigned to indicate flow rates and control set flowrates of gases.

Each of these units incorporates an advanced straighttube sensor in conjunction with flow passage elementsconstructed of stainless steel.

LED readouts of command modules are supplied with0 to 100 percent calibrations. Zero and span adjust-ments are conveniently accessible from outside of thetransmitters.

Design Features

Rigid metallic construction.Maximum pressure of 1000 psig (70 bars).0-5 Vdc or 4-20mA signals.Leak integrity 1 x 10-9 smL/sec of helium.Accuracy of ±1% F.S.Totalizer option.Circuit protection.

Principles of OperationMetered gases are divided into two laminar flow paths,one through the primary flow conduit, and the otherthrough a capillary sensor tube.

Both flow conduits are designed to ensure laminar flowsand therefore the ratio of their flow rates is constant.

Two precision temperature sensing windings on the sen-sor tube are heated, and when flow takes place, gascarries heat from the upstream to the downstream wind-ings. The resultant temperature differential is proportion-al to the change in resistance of the sensor windings.


Output signals of 0 to 5Vdc or 4 to 20mA are generatedindicating mass molecular based flow rates of themetered gas.

AF mass flow meters and controllers are designed to meter andcontrol flow rates of gases.

AF mass flow meters and controllers are available with flowranges from 10 sccm to 100LPM [N2]. Gases are connected bymeans of 1/4”, 3/8”, or optional 1/8”compression fittings. Thesecontrollers may be used as bench top units or mounted bymeans of screws in the base.

Transducer power supply ports are fuse and polarity protected.

Leak Integrity

1 x 10-9 smL/sec of helium max to outside environment.

Mass Flow Systems

Complete Mass Flow Systems include Command Modules,transducers and cables. Command modules contain appropri-ate power supplies, digital panel meters with 3-1/2” digit LEDreadouts and high precision potentiometers.

External RS-232 or RS-485 are optional.

Switches in the front panels of CommandModules select LOCAL or REMOTE referencesignals, analog outputs are accessible throughconvenient 9 pin D-connectors.

In AFC mass flow controllers the combined gas streams flowthrough a proportionating electromagnetic valve with an appro-priately selected orifice. The closed loop control circuit continu-ously monitors the mass flow output and maintains it at the setflow rate.

Flow rates are unaffected by temperature and pressure varia-tions within stated limitations.

AFC mass flow controllers include an electromagnetic controlvalve that allows the flow to be set to any desired flow rate with-in the range of the particular model. The valve is normallyclosed as a safety feature to ensure that gas flow is shut off incase of a power outage.

In Internal reference mode, the user sets the control sig-nal with SDPROC controls (via front panel keypad, RS-232 or Ethernet interface).

In EXTERNAL REFERENCE MODE, the user sets thecontrol signal from a remote location (via the DATAIN/OUT 25-pin "D"-connector on the rear panel).

In PROGRAM MODE the set point signal will be driven byuser's custom program stored in the EEPROM. There arethree Program modes: BATCH, TIMER and RATIO*.*RATIO mode not available for one channel module.

PROGRAMMABLE TIMER FLOW CONTROLThe Timer Flow Control allows execution of custom, userpreset program of up to 96 steps. Each step can be pre-programmed for a particular date, time, and set point value.Every step has two fields: starting date, time and set pointin % F.S.

RATIO FLOW CONTROLThe Ratio Flow allows controlling flow of the mixture of up tofour different gases (for 4 channel Command Module) withpreset values of the ratio in % for each channel.The flow rateof the mixture can be incremented or decremented bychanging the set point of the master channel #1.

FLOW ALARMSHigh and Low gas flow ALARM limits can be prepro-grammed for each channel. ALARM conditions becometrue when the difference between current readings andinstalled set points are equal or more than correspondingvalues of high and low alarm levels. Alarm action can beassigned with preset delay interval (0-3600 seconds) toone of the following:

Contact closer (separate for High and Low alarm)Buzzer audible signalValve shut down (Close)

CONTACT CLOSURESTwo sets of dry contact relay outputs for each channel areprovided to actuate user supplied equipment. The relayscan be assigned to switch when a specified event occurs(e.g. when a low or high flow alarm limit is exceeded orwhen the totalizer reaches a specified value).

TOTALIZERThe total volume of the gas is calculated by integrating theactual gas flow rate with respect to time. Both keypad menuand digital interface commands are provided to:

Programming

It is easy to program the SMART DPROC using a log-ically organized, modular menu. The operator quicklyaccesses a desired function by branching through themulti-level tree structure, rather than scrolling throughthe entire menu. RS-232 serial communication inter-face is standard for all models and supported via a 9pin "D"-connector on the back panel of the CommandModule. RS-232 Software interface commands setallows communications with the unit using either a cus-tom software program or a "dumb terminal" and pro-vide complete control over all modes and functions.

PROGRAMMABLE BATCH FLOW CONTROLThe Batch Flow Control allows execution of custom,user preset program of up to sixteen steps. Duringexecution of the program the user can activate ordeactivate the LOOP mode. Various flow configura-tions may be preprogrammed: ramping, pulsing, lin-earized increasing and/or decreasing of the flow.

Optional built-in Ethernet interface allows accessingany Internet-connected SDPROC from a browser onyour work station, PC, or laptop computer. Regardlessof where you are, your Command Module is as closeas the nearest browser! There are two levels ofEthernet based Remote Controls: HTML web serverand TELNET. The HTML web server, which is hostedon the Command Module lets one view CURRENTFLOW RATE, CONTROL VALVE MODE and/or SETPOINT, MONITOR TOTALIZER READING FORSELECTED CHANNEL. The TELNET console pro-vides complete control over all modes and functionsand using the same Software interface commands setas the RS-232 communication interface.

Design Features

ENGINEERING UNITSThe flow set points, measured gas flow and associat-ed totalizer data are scaled directly in engineeringunits via front panel keypad, RS-232 or Ethernetinterface. The following units of measure are support-ed: %F.S., SLPM, SLPH, SCCM, SCCH, SCFM,SCFH, SCMM, SCMH, LBPM, LBPH, GRPM, GRPH.

USER SELECTABLE REFERENCE FOR SET POINTThe INTERNAL, EXTERNAL, PROGRAM refers tothe point of origin for the Set Point signal.

Principles of OperationVortices are created when a fluid passes around a bluffbody as shown below. Vortices are alternately shed on eachside of the body, 180 degrees out of phase to each other,resulting in an oscillating pressure gradient. As flow increas-es the frequency of vortices increases in proportion to theincreased flow thereby creating a linear relationship.Aalborg’s unique dual signal processing technology inde-pendently measures each vortex on either side of the bluffbody and filters out non-flow noise. This results in less noiseand higher accuracy throughout the flow range.

Dual signal processing technology independently measureseach vortex providing increased accuracy and turndown.

Benefits

Functional Specifications

RELIABLE No moving parts to wear or fail.Electronics can be remote mounted up to 100 ft. (30.5 m)No fluid to sensor contact.No holes to clog.

WIDE RANGEABILITY

High flow turndown ratio up to 80:1. Dual signal processing technology improves accuracy at low flows.

HIGH ACCURACY

0.5% of rate.Increased noise cancellation as a result of dual signal processing technology.

Vortex Insertion Flow Meter VXPrinciples of OperationVortices are created when a fluid passes around a bluffbody as shown below. Vortices are alternately shed on eachside of the body, 180 degrees out of phase to each other,resulting in an oscillating pressure gradient. As flowincreases the frequency of vortices increases in proportionto the increased flow thereby creating a linear relationship.Aalborg’s unique dual signal processing technology inde-pendently measures each vortex on either side of the bluffbody and filters out non-flow noise. This results in less noiseand higher accuracy throughout the flow range.

Dual signal processing technology independently measureseach vortex providing increased accuracy and turndown.

Design Features

Leak Integrity 1 x 10-9 sccm.Rigid metallic construction.Gas and liquids.Max pressure of 500 psig (34.8 bars).

Principle of Operation

A variable stroke electromagnetic valve featuring a valveseat design which permits increasing or decreasing flowrates of liquids or gases through it in proportion to variableinput power.

Regulator SystemsComplete flow regulating systems include a PSV electro-magnetic valve connected to a pulse width modulatedPSV-D Driver Module. For details see Driver Module de-scription. Optional external RS-232 or RS-485 modules areavailable. (See page 11).

42

PSV Proportionating Electromagnetic Valves are designedto respond to variable power inputs to regulate the flow ofliquids and gases proportionately.

For added safety PSV valves are normally closed (NC)when deenergized. They can also serve as “ON-OFF”valves. For control functions see the PSV-D Driver Module.

Flow is controlled by increasing or decreasing the voltageapplied to the coil. This causes a magnetic force which rais-es the core and allows gas to flow.

PSV valves, constructed of stainless steel are available infive different sizes covering flow ranges from 3.5 sL/min -100 sL/min air and 125 mL/min - 2.85 L/min H2O.

Pulse Width Modulated Driver Module PSVD

Jumper selectable output power allows a choice of dcvoltage range for cooler more efficient operation, as afunction of flow rates.

Internal resettable fuse protects electronics and rectifiercircuits, prevents polarity reversal damage.

The maximum output voltage supplied to the PSV Valvecan be set or changed in the field to allow for optimal useof the input reference signal to output voltage based onthe specific flow rate and operating pressure applied tothe valve.

Pulse Width Modulated Driver Module shown with PSV valve

PSV-DPulse width modulated PSV-D Driver Modules regulatethe power supplied to PSV Regulating valves based on areference signal.

Set-point signals, 0 - 5 Vdc or 4 - 20 mA, input areemployed to control the output pulse width modulatedvoltage at a fixed frequency (≈30KHz) and amplitude.Incoming power to the valve coil is applied and discontin-ued for predetermined periods of time by a low loss solidstate switching element.

As incoming power is applied, energy in the inductive coilsincreases and when it is discontinued energy stored in thecoil maintains the magnetic flux level required to hold flowat the controlled rate. This cycle takes place many thou-sands of times per second.

The wide range of power input feature convenientlyaccommodates 12 to 32 Vdc sources.

The Auto-Select feature of the Driver Module recognizesthe type of reference signal received and defaults to 0 - 5Vdc if both signals are provided.

CONNECTION: 9-pin male “D” subconnector for input/output signals.

POWER INPUT REQUIRED:+12 to 30 Vdc 1A @ 12 Vdc, 0.5A (not supplied) @ 24 Vdc via 9-pin “D”-connector or dc power jack (center positive).

INPUT SIGNAL: Auto-Select feature allows circuit to recognize which analog input reference (0 to 5 Vdc or 4-20 mA) signal is provided.

TTL ON/OFF: Jumper selectable LOW (0 Vdc) OFF-HIGH (5 Vdc) on, or reverse, to select valve ON/OFF status.

VALVE OUTPUT POWER: Jumper selectable to +15, +22, and +29 Vdc with adjacent potentiometer to obtain ±2 Vdc.

FUSE RATING: An internal resettable 1.6A fuse protects the electronicson the power input.

POLARITY PROTECTION: Internal rectifier circuit protects from reversed polarity on the power input.

OPERATING TEMPERATURE:0OC (32OF) to 50OC (122OF).

DIMENSIONS:3” (7.62mm) wide x 3” (7.62mm) deep x 1” (25.4mm) high.

CE COMPLIANCE :EMC Directive 89/336/EEC EN55011:1991 Group 1, Class A EN50082-2:1995.

Design Features

High precision two-way metering valves in aluminum or 316 SS for air/water.

Unparalleled precision and resolution in controlling flow rates (0.0005” per step resolution)

Operate continuously without overheating. Eliminates coil heating problems associated with solenoid designs.

Operation

When the "DIRECTION" is set LOW (GND) the valve spindle travels downward (closes), when it is set HIGH, thevalve spindle moves upward (opens). The "SPEED" voltage on pin 4 determines how quickly the valve opens or clos-es. The signal amplitude for the "SPEED" control signal must remain within the limits of 0 to +5.0 VDC. It may be nec-essary to override "DIRECTION" and "SPEED" signals with the preset (2.75 Vdc) speed control signal.

This can be accomplished with valve CLOSE and PURGE control signals (open collector NPN compatible). In orderto CLOSE the valve, pin 3 on the 9-pin "D" -connector has to be connected to GND (pin 2). A GREEN light on the topof the valve will indicate a CLOSED valve condition. In order to PURGE the valve, pin 7 on the 9-pin "D"-connectorhas to be connected to GND (pin 2). A RED light on the top of the valve will indicate a fully OPEN valve condition.

General Description

A line of electronic two-way metering needle valves ispresented. High precision linear stepping motors drivethe valve spindle.

The resolution of the stepping motor driven needles is0.0005"/step. Low differential pressure valves, may beoperated continuously (100% duty cycle).Valves stay inposition as when de-energized.

Advantages over solenoid operated valves include cooloperations, i.e. there are no control operating problemsdue to coils heating up, extremely fine resolution, verylow differential pressures and high operating pressures.Valves are controllable by TTL compatible logic leveland analog 0 to 5 Vdc signals.
