Gastransport Nord GmbH / (GTG) – Measurement and Control Technology

For natural gases in practice usually volumetric measurement and differential pressure method can be used. Typical instruments are iris, displacement, turbine, ultrasonic and eddy gas meters.

Our contact with calibration services. In legal metrology in the gas high-pressure area currently time series circuits in particular turbine and ultrasonic flowmeters are used. These are just some of the traits that help us support you — for the entire lifecycle of your gas measuring devices. Measurement nozzle for heating system throughput – has bores either side of aperture leading to differential press meter adaptor.
