4.4 Setting the maximum pumping rate
.
1.
Fill a calibration cylinder (best to use water, not chemical for testing and calibration)
2.
Run the pump at full speed and time the drawdown for 30 sec. (from the zero level in the cylinder)
3.
Note the level in the calibration cylinder when 30 seconds elapses. That will be your full scale pumped flow rate.
4.
Divide the full scale pumped flow volume by the maximum hertz setting for your pump* to get volume for 1HZ.
EXAMPLE
:
1. Assuming the full speed drawdown test above shows 50GPH and your maximum pump frequency is 80HZ*
2. Then divide 50 / 80 = 0.625 GPH per 1 Hz.
3. If your desired maximum pumping rate is to be 35GPH then divide 35 / 0.625 = 56HZ.
4. Change Menu 3.02 to 56.
5. Now a 20mA speed control input to the pump will equal 35GPH pumping rate.
