Abstract
A system and method for detecting and mitigating a suction condition are disclosed. The method may include characterizing pump waveform signal, identifying and evaluating a characteristic of the waveform for an existence of a suction condition. In various embodiments, a change in harmonic spectral distribution will identify a probability of a suction condition. A speed of the pump may be adjusted to mitigate the suction condition.
