Abstract
A self-contained measuring device indicates three parameters necessary to the determination of operating performance of an electrical analog of a reciprocating gas compressor or pump. A first portion of the device provides for measuring any horsepower changes during operation as a percentage of the ideal operating conditions. A second portion of the device measures the discharge current from the analog cylinder. A third portion of the device measures the phase between a sinusoidal reference signal and a non-sinusoidal periodic driving signal. The phase measuring portion of the device is used primarily for initial setup of the analog, while the first and second portions are used both during setup and during normal operation.
