Turbine Flow Meter Manual 05/13 - 0721-1 / 13518

Page 28

5.2.2 Procedure

1. Determine the input frequency required to simulate the desired maximum flow rate using the

equation below:

2. Remove the flow meter from the pipe and make sure the electrode and the surrounding area

are dry.

3. Choose the input frequency range (Hz) from the table on the next page and set the appropriate

range selection jumper. Refer to Appendix A for the internal wiring diagram of your model.

4. Connect the pulse generator output lead to the test signal input lead on the analog card, and

connect the pulse generator ground lead to the black ground wire in the flow meter cable. Set
the output to a 15 V P-P square wave at the frequency determined in step #1.

5. Set the DC voltmeter to the 0-10 V scale and connect the (+) lead to the brown wire in the flow

meter cable. Connect the (-) lead from the voltmeter to the black ground wire in the flow meter
cable.

6. Connect the red and black wires in the flow meter cable to the (+) and (-) terminals of the 24 V

power supply respectively. Apply power.

7. Adjust the span potentiometer on the analog card to produce a 10 V reading on the voltmeter.

NOTE: The frequency ranges in the table below are a starting point, and since they vary with
electronic component tolerance, it may be necessary to change the jumper position once rescaling
is started. If the range of adjustment of the span potentiometer is not sufficient to produce the
desired 10 VDC, change the jumper position as follows:
VOLTAGE READING TOO HIGH: Choose the next lower jumper position.
VOLTAGE READING TOO LOW: Choose the next higher jumper position.

8. The flow meter is now rescaled. Disconnect all equipment, replace the cover and reinstall the
flow meter.

Where:
F = Input Frequency (Hz)
R = Maximum Flow Rate
MF = Meter Factor*
*The meter factor is written on a calibration tag attached to each meter and is also
recorded on the calibration data sheet. Use one of the three formulas provided based
on the engineering units for the meter factor. Please contact ONICON if you cannot
locate the meter factor, or if you wish to use the meter in a different pipe size.

For l/s

For M3/hr
