515-GC01 – Ideal Gas Computer – Quadrature Input

Ideal Gas Computer – Quadrature Input

The 515-GC01 application measures the volume, corrected volume and mass of a general gas. The instrument uses a frequency volume flow input and analog temperature and pressure sensor inputs.

The instrument is compatible with a wide range of flowmeter frequency outputs. Millivolt signals, reed switches, Namur proximity switches or pulse trains can be selected via its smart front-panel programming.

The properties of 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.

Calculations

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

Equations of state:
• Ideal Gas
• Redlich-Kwong
• Soave-Redlich-Kwong
• Peng-Robinson
