Standard for calibration of gas flow meters

system must be operating with a pressure range of at least 0 - 60 barg and with flow rates of at least 1 - 100 Sm3/h. A design could be a primary standard based on the measurements of pressure, volume, temperature, and time – pVTt. An example of a pVTt system design is included in Annex 2+3 , colle

cted volumes will be typically up to 850 litres. The Justice Department is open to other primary or secondary standard designs.
