摘要:
A pumping system for at least one aquatic application comprises a motor coupled to a pump and a controller in communication with the motor. The controller may be adapted to determine a first motor speed, determine a present flow rate using curves of speed versus flow rate for discrete power consumptions, generate a difference value between the present flow rate and a reference flow rate, and/or drive the motor at a second motor speed based on the difference value until reaching a steady state condition.
