Apparatus and method for controlling a pump system
First Claim
1. A controller for controlling operating parameters associated with fluid flow, speed or pressure of a centrifugal pump for pumping fluid, wherein at least one sensor is coupled to said pump for generating a signal indicative of a sensed operating condition, said controller comprising:
- a storage device for storing data indicative of an at least one operating condition; and
a processor in communication with said sensor, the processor utilizing said at least one sensor signal and said stored data indicative of said at least one operating condition to generate a control signal which is applied to said pump, for correcting the speed thereof in order to maintain a requisite pump flow or pressure, said control signal including a stability factor that prevents overcorrection of said pump speed.

Abstract
A controller for controlling operating parameters associated with fluid flow, speed or pressure for a centrifugal pump for pumping fluid, wherein at least one sensor is coupled to the pump for generating a signal indicative of a sensed operating condition. The controller comprises a storage device for storing data indicative of at least one operating condition and a processor in communication with the sensor and operative to perform an algorithm utilizing the at least one sensor signal and the stored data indicative of the at least one operating condition to generate a control signal, wherein the control signal includes a correction factor between 0.1 and 1.0 that is applied to the pump controlling algorithm in order to prevent overcorrection.
