This unit consists of two parallel lines of measurement and allows the measurement and the transfer of gas flow in accordance with the directives UNI EN ISO 5167-2-2004.
The method of calculation is based on the use of diaphrams with calibrated orifice and differential pressure transmitters, temperature and pressure of the line.
A gas chromatograph performs the analysis of the characteristics of the gas flow and interfaces with a computer that provides the measurement of flow rates and volumes in Sm3, calculated at reference conditions of 15°C and 1.01325 bar.
