Abstract
An apparatus for measuring the work produced by a compressor comprises pressure sensors for measuring the suction and discharge pressures of the compressor and a device for measuring the operating speed of the compressor. The apparatus further comprises a data processor for receiving signals representative of the suction and discharge pressures of the compressor and its operating speed, and generating a signal representative of the work performed by the compressor during a predetermined time interval. Desirably, the data processor is designed to integrate the work output of the compressor over a series of time intervals to generate a cumulative horsepower-hour reading for the compressor over an extended period of time.
