ABSTRACT:
A fluid pump speed controller apparatus for ensuring adequate system fluid pressure while minimizing energy consumption. The fluid pump speed controller has an adjustable frequency motor drive and control circuits to vary fluid pump motor speeds based on system fluid demand, monitored by a sensor. The control circuits set the pump speed, based on input from the sensor. The control circuits also set parameters in the control circuit logic, and are capable of self calibration and controlling multiple fluid pumps.
