Contrec 515 – GC06

Ideal Gas Computer - DP Meter (Volumetric Span)

The 515 GC06 application measures the volume, corrected volume and mass of a general gas. The instrument uses single of stacked differential pressure volumetric flow inputs and analog temperature and pressure sensor inputs.

The instrument calculates the flow according to generic differential pressure equations and incorporates the conditions at which the flowmeter was calculated.

The properties of a gas are calculated using common industry standard equations of state. These equations use a simplified set of parameters to quickly and accurately determine the value of compressibility and actual quantity of gas.


A variety of calculations are available to suit the nature of the gas and the measurement conditions. The calculations are valid for the vapour phase of gas.

Equations of state:
