Flow Control

A pumping system for at least one aquatic application, the pumping system comprising:

• a motor coupled to a pump;
• and
• a controller in communication with the motor;
• the controller adapted to determine a first motor speed of the motor;
• the controller adapted to determine a reference power consumption using a reference flow rate and a curve of speed versus power consumption for the reference flow rate;
• the controller adapted to generate a difference value between the reference power consumption and a present power consumption;
• the controller driving the motor to reach a steady state condition at a second motor speed based on the difference value.
