1. Apparatus for measuring the throughput of a gas compressor, said apparatus comprising:
- (a) an engine operatively connected to said compressor and powered by the same gas being compressed by the compressor;
(b) a first pressure sensor means for measuring the suction pressure of gas entering said compressor and generating a first signal representative of said suction pressure;
(c) a second pressure sensor means for measuring the discharge pressure of gas leaving said compressor and generating a second signal representative of said discharge pressure;
(d) a data storage means for storing signals representative of the piston displacement and piston clearance; and
(e) a calculating means arranged to receive said first, second and stored signals and to calculate therefrom a fourth signal representative of the throughput by said compressor.

Abstract
An apparatus for measuring the throughput and average suction and discharge pressures of a compressor comprises pressure sensors for measuring the suction and discharge pressures of the compressor and in one embodiment a device for measuring gas temperature. The apparatus further comprises a data processor for receiving signals representative of the suction and discharge pressures of the compressor and generating a signal representative of the throughput of the compressor during a predetermined time interval.
