Accurate Differential Pressure Measurement

Meriam M201According to Meriam Process Technologies, its M201 enhanced rotary gas meter tester accurately measures the pressure drop across rotary vane positive-displacement meters. Furthermore, the M201 boasts:

  • Special firmware designed to mathematically average differential pressure readings over the test period — when the averaging feature is active, the M201 takes pressure readings over the user-defined period of time and, at the end of the test interval, displays the true average of the readings, thereby minimizing the effects of pulsating pressure and surges in flow, and guaranteeing a consistent and operator-independent test methodology.
  • The ability to display minimum and maximum pressures recorded during the test period.
  • Simple use — press the start/stop key to initiate the test and press it again to stop the test. The capability to calculate and display the mathematical average of the differential pressures over the user-defined test period along with the test time.
  • A tailored design that is intended for lines with pressures to 150 PSIG — it is not designed for transcontinental gas lines where higher line pressures are present.
