摘要
The present invention is directed to a centrifugal pump wherein voltage and current data are detected from voltage and current sensors in the pump motor. A power signal is then generated from the voltage and current data and spectrally analyzed to determine the low flow or cavitation in the pump. As such, unwanted operational conditions resulting from improper pump operation may be detected and a warning or maintenance flag provided without additional transducers and other instruments on the motor or pump.
