Gas metering station

Before ordering gas meter station there we have to specify some of the data required in the engineering process. tkenik process data are as follows:

Line Size (inch)

Operating Temperature : Max. , Min., Normal (deg F)

Operating Pressure (upstream) : Max. , Min., Normal (Psig) see pressure on gas source.

Operating Pressure (downstream) : Max. , Min., Normal (Psig) see pressure on gas to customer/User

Flowrate: Max. , Min., Normal (MMSCFD)

Molecular Wight of Gas : 16.4 (ussualy) 

Cp/Cv Ratio

Compressibility Factor: 0.997 (ussualy) 

Viscosity , µ at op.condition (CP) : 0.0129 (ussualy)

Specific Gravity of gas (SG) : 0.66 

Piping Class

Instrument type: orifice plate, etc 

A data processing techniques should be also equipped with a PID drawing as follows:
