FLOW CONTROL
First Claim
1. A pumping system for moving water of a swimming pool, the pumping system including:
- a water pump for moving water in connection with performance of an operation upon the water;
a variable speed motor operatively connected to drive the pump;
means for determining a first motor speed of the motor;
means for determining a value indicative of a flow rate of water moved by the pump;
means for determining a first performance value of the pumping system, wherein the first performance value is based upon the determined flow rate;
means for determining a second performance value of the pumping system;
means for comparing the first performance value to the second performance value;
means for determining an adjustment value based upon the comparison of the first and second performance values;
means for determining a second motor speed based upon the adjustment value; and
means for controlling the motor in response to the second motor speed.

Abstract
A pumping system for moving water of a swimming pool includes a water pump and a variable speed motor. The pumping system further includes means for determining a first motor speed of the motor, means for determining first and second performance values of the pumping system, and means for comparing the first and second performance values. The pumping system further includes means for determining an adjustment value based upon the comparison, means for determining a second motor speed based upon the adjustment value, and means for controlling the motor in response to the second motor speed. In one example, the pumping system includes means for determining a value indicative of a flow rate of water moved by the pump. In addition or alternatively, the pumping system includes a filter arrangement. A method of controlling the pumping system for moving the water of the swimming pool is also disclosed.
