Abstract
A pumping system for at least one aquatic application. The pumping system includes a pump, a motor coupled to the pump, a filter coupled to the pump, and a controller in communication with the motor. The controller is configured to make a sensorless determination of a current value of a water flow rate based on an input power to the motor, drive the motor speed to maintain the water flow rate at a first constant value during a first time period, and drive the motor speed to maintain the water flow rate at a second constant value during a second time period.
