Turbine Housing

Computer Electronics(sold separately)

Liquid flows through the turbine housing caus-ing an internal rotor to spin. As the rotor spins,an electrical signal is generated in the pickupcoil. The electrical signal provides the outputnecessary to operate the on-board computerelectronics for local indication directly on theturbine or one of several accessory modulesthat transmit the signal to external equipment.

Upon receipt, examine your meter for visibledamage. The turbine is a precision measuringinstrument and should be handled as such.Remove the protective plugs and caps for athorough inspection. If any items are damagedor missing, contact your distributor.

Make sure the turbine model meets your spe-cific needs. Refer to the Specifications Sec-tion and confirm the following:

1. The flowrate is within the limits of yourmodel.

2. The liquid is compatible with the turbine’swetted components.

3. The system’s pressure does not exceed theturbine’s maximum pressure rating.

Information specific to your particular turbine,including serial number, model number,manufacturing date, and K-factor is found onthe surface of the turbine.

SN = Serial Number, a 6-digit number thatidentifies this particular turbine.

MODEL = Model Number begins with aletter indicating the housing material.

A for AluminumB for BrassS for Stainless Steel

Two digits follow the material code indicat-ing the size.

05 = 1/2 inch 15 = 1-1/2 inch07 = 3/4 inch 20 = 2 inch10 = 1 inch

The final letter indicates the type of thread.F for FlangeN for NPTI for ISO

MFG DATE = Manufacturing Date indi-cating the week and year of manufacture.

KF = K-Factor given in pulses per gallon(PPG).

For your future reference, it might be usefulto record this information in the manual in caseit becomes unreadable on the turbine.

Turbines are designed to measure flow in onlyone direction. The direction is indicated bythe arrow cast-molded in the turbine outlet. Ifthe opposite direction is desired, and you areusing on-board computer electronics, rotatethe computer electronics 180 degrees prior toinstallation.

Flow altering devices such as elbows, valves,and reducers can affect accuracy. The follow-ing guidelines are given to enhance accuracyand maximize performance. Distances givenhere are minimum requirements; double themfor desired straight pipe lengths.

Upstream from the turbine, allow a minimumstraight pipe length at least 10 times the inter-nal diameter of the turbine. For example, withthe 1 inch turbine, there should be 10 inches(25.4cm) of straight pipe immediately up-stream. The desired upstream straight pipelength is 20 inches (50.8cm).

Downstream from the turbine, allow a mini-mum straight pipe length at least 5 times theinternal diameter of your turbine. For example,with the 1 inch turbine, there should be 5inches (12.7cm) of straight pipe immediatelydownstream. The desired downstream dis-tance is 10 inches (25.4cm).

A typical back pressure of 5 to 50 PSI (0.34to 3.4 bar) will prevent cavitation. Create backpressure by installing a control valve on thedownstream side of the meter at the properdistance detailed above.

Foreign material in the liquid being measuredcan clog the turbine’s rotor and adversely af-fect accuracy. If this problem is anticipated orexperienced, install screens to filter impuri-ties from incoming liquids.

INSTALLATION

4

These turbines are tested and calibrated atthe factory using state-of-the-art calibrationprocedures and test equipment.

To ensure accurate measurement, remove allair from the system before use. To purge thesystem of air:

1. Ensure some back pressure exists on theturbine in the line.

2. Open the discharge valve or nozzle andallow fluid to completely fill the system.Make sure the stream is full and steady.

3. Close the discharge valve or nozzle.

4. Start normal operations.

Each turbine contains a removable backcoverplate. Leave the coverplate installedunless accessory modules specify removal.

Connections1. To protect against leakage, seal all

threads with an appropriate sealing com-pound. Make sure the sealing compounddoes not intrude into the flow path.

2. Make sure the arrow on the outlet ispointed in the direction of the flow.

3. Tighten the turbine onto the fittings. Usea wrench only on wrench flats.

NOTE: If connecting to new male threads,burrs and curls can adversely effect ac-curacy. Correct the problem prior to tur-bine installation.

It is strongly recommended that accuracy beverified prior to use.

Flange ConnectionUse a gasket between the meter flange andmating flange. Determine the material of thegasket based on the operating conditions andtype of fluid.

NOTE: Do not over tighten the flange bolts.This may cause the gasket to be com-pressed into the flow stream and maydecrease the accuracy of the meter.

Verify AccuracyBefore use, check the turbine’s accuracy andverify calibration.

1. Make sure there is no air in the system.

2. Measure an exact known volume into anaccurate container.

3. Verify the volume against the readout orrecording equipment.

NOTE: If necessary, use a correction factorto figure final volume.

For best results, accuracy should be verifiedperiodically as part of a routine maintenanceschedule.

Remove the Turbine

1. Drain all liquid from the turbine. Wearprotective clothing as necessary.

2. Loosen both ends of the turbine. Use awrench only on the turbine’s wrenchflats.

3. If the turbine is not immediately installedagain, cap lines as necessary.

Replace Internal Parts

1. Remove the turbine from the system asdetailed above.

NOTE: Carefully notice the orientation of allinternal parts as they are removed, espe-cially the orientation of the rotor to theflow direction arrow. See Figure 2.

MAINTENANCE

2. Using a small tool such as a screwdriveror awl, gently pry one retaining ring fromits groove. Remove the support. If nec-essary, use needle nose pliers. Little orno force should be required.

3. Carefully remove the rotor.

CAUTION: Handle the rotor carefully.Even small scratches or nicks can affectaccuracy.

4. Turn the turbine over and remove theother retaining ring. Remove the othersupport.

5. Clean, as detailed below, or discard asnecessary.

6. Replace one support and retaining ring.Parts should drop easily into place withlittle or no force.

7. Install the rotor. Make sure the wide endof the rotor’s blades faces the flow di-rection. See Figure 3.

8. Turn the turbine over and drop the sec-ond support into place. Put the final re-taining ring into position.

9. Reinstall the turbine, purge the systemof air, and verify accuracy before use.

Clean the TurbineDuring use, the turbine should be kept fullof liquid to ensure that drying does not occurinside the turbine. If drying or caking shouldoccur, the rotor will stick or drag, affecting ac-curacy. To determine if the rotor is stuck or drag-ging, gently blow air through the meter andlisten for the quiet whir of the rotor.

CAUTION: Never blow compressed airthrough the meter. It could damage therotor.

1. Remove the turbine from the system fol-lowing the directions above.

2. Carefully clean residue off all parts. Re-move internal parts as detailed above.Note orientation carefully for correct as-sembly. Internal parts can be soaked for10 to 15 minutes in compatible cleaningsolutions. Use a soft brush or small probeto carefully remove residue from the ro-tor.

3. When the rotor turns freely, assembleand install it again following the instruc-tions above.
