Abstract
A positive displacement pump monitor. The monitor includes a sensor coupled to a housing of a pump for obtaining acoustic data therefrom. A proximity switch may be simultaneously used to keep real time timing information relative to the cycling of the pump. A data processor of the monitor may then be employed to analyze acoustic data and timing information to distinguish acceptable noise from leak information. An operator thereby may be warned of the presence of a leak in the pump.
