100 Hz Signal (Higher flow rate example)
2.6 Alternate Method for Flow Meter Signal Verification (if multi-meter is not available)
Use an analog GPM gauge in proximity to the flow meter, to find flow rate.
2.7 Convert the U1-24 (Hz) display to GPM for comparison.
Because the U1-24 display reads in HZ and the analog gauge reads GPM we must convert the
U1-24 display to GPM for comparison.
Multiply the U1-24 display value by 60 secs 
60 Hz x 60 = 3,600 pulses per minute (PPM)
2.8 Divide 3,600 PPM by 25.228 PPG. 25.228 is the calibrated flow meter output for an
AG2000-300 meter 
3600 PPM/25.228 PPG = 142.7 GPM @ 60 Hz
*Note: PPG can be found on the AG2000 flow meter spec sheet.
2.9 Compare the calculated result from STEP 2.8, to the pipe mounted analog gauge GPM
value. The two values should match.
2.10 Recheck all electrical connections for a wiring error and make corrections if a substantial
difference in the compared readings exists (no match).
