The MTM volume flow meter is a turbine gas meter for the custody transfer of natural gas under MID EN 12261 (2007) and OIML R137 1&2 (2012). The measuring cartridge of the MTM turbine meter is exchangeable for different pressure housing designs. It can be calibrated in each diameter size to the different G-ratings. Operating pressures up to 100 bar and a volume flow rates of 5 m³/h up to 6500 m3/h depending on the different meter sizes at operating conditions are possible.
