A system and method for monitoring and controlling a pump includes defining processing targets, deriving a first actuator control signal Yc from the processing targets, and deriving actual operating parameters. Additionally, the actual operating parameters are compared to predefined system and pump limits to determine a second actuator control signal Y'c, the actual operating parameters are compared to predefined fluid limits to determine a third actuator control signal Y&#x2033;c, the actual operating parameters are compared to predefined normal processing limits to determine a fourth actuator control signal Y&#x2032;&#x2033;c, and the actual operating parameters are compared to at least one predefined abnormal processing limit to determine a fifth actuator control signal Y&#x2033;&#x2033;c. The most conservative actuator control signal is then determined, and the pump is driven in accordance with the most conservative actuator control signal.

Intelligent pump monitoring and control system

A system for monitoring wear of pump casing liners is disclosed. The system may include a wear sensor disposed in proximity to the pump casing liner so that the sensor wears at substantially the same rate as the lining. The wear sensor may include a plurality of circuit loops having different lengths. As the pump casing liner and the sensor wear during use, the plurality of circuit loops are sequentially breached. A control system monitors the signals from the plurality of circuit loops to develop liner wear information. This information is employed to signal a user when one or more predetermined wear thresholds are exceeded.
