Standard for calibration of gas flow meters

e operating with a pressure range of at least 0 - 60 barg and with flowrates 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 , collected volumes wi

ll be typically up to 850 litres. Justervesenet is open to other primary or secondary standard designs.
