FORWARD Pg.1 A. PRINCIPLE OF OPERATION 1. The precision turbine flowmeter is a volumetric flow measuring device. 2. The flowing fluid engages the vaned rotor causing it to rotate at an angular velocity proportional to the flowrate. 3. The angular velocity of the rotor results in the generation of an electrical signal (AC sine wave type). Summation of the pulsing electrical signal relates directly to the flow rate. 4.
PRE-INSTALLATION INSPECTION Pg.2 Your SPONSLER PRECISION TURBINE FLOWMETER is a measuring instrument capable of providing you with high precision performance over a long period. It should be treated with care and not subjected to rough handling. 1. Unpack carefully and verify the information contained on the packing slip for proper MODEL Number, SERIAL Number, and CALIBRATION Data. 2. Remove the instrument from the plastic packaging and remove the endfitting protectors from the flowmeter housing. 3.
B. PIPING Pg.3 1. General Piping Considerations- As explained in the FORWARD, the fluid moving through the flowmeter engages the angled blades of the turbine rotor. Thus the rotational velocity of the rotor is a function of the fluid velocity and the blade angle engagement. Swirl present in the fluid ahead of the meter can change the effective angle of engagement and, therefore, cause a deviation from the supplied calibration (done under controlled flow conditions).
Pg.4 3 TYPICAL METERING RUNS METERING LOCATION UPSTREAM DOWNSTREAM Pipe fitting immediately preceding metering location Pipe fitting immediately following metering location.
TYPICAL FLOWSTRAIGHTENER SECTION 1/5 DIAMETER Pg.5 2 DIAMETERS Flowstraightener- A full cluster of thin wall tubes fixed within a section of pipe. The length of the internal tubes is equal to 2 diameters of outer pipe. The diameter of internal tubes is equal to approximately 1/5 the inside diameter of outer pipe. This requires 18 to 20 such tubes.
