Gas flow meters
Three complementary measurement technologies - ultrasonic, rotary and turbine - engineered for natural gas, biomethane and hydrogen blends, from low-pressure distribution to high-pressure transmission.
Ultrasonic, rotary and turbine technologies for every gas measurement task.
Our gas flow meter portfolio covers the full operating envelope of the European gas grid. From the patented Transus LPM-zD ultrasonic meter - a true zero-D design that eliminates upstream and downstream straight-pipe requirements - to the FMG rotary meters, up to 1600m³/h and turbine meters up to 25000m³/h (high and low pressure), we offer one of the broadest fiscal-grade meter ranges in Europe.
Each project can be supported with the required technical documentation, metrological certificates and traceable calibration reports. Where specified, witnessed calibration can be arranged at recognized test facilities such as Euroloop, FORCE Technology, DNV or PIGSAR, subject to meter type, size and project requirements. All meters integrate seamlessly with Ex-i flow computers and operator SCADA systems for end-to-end metrological accountability.

Where it's used
Flow meters from the Gas Measurement Group are deployed across the global energy value chain - from transmission networks to industrial end-users.
Gas transmission & TSO
Custody transfer at border and entry stations, fiscal balancing and grid-quality measurement at high pressures.
Distribution (DSO)
Pressure-reduction stations, district metering and zero-D installations where straight pipe is unavailable.
Industrial energy
Delivering reliable, high-accuracy measurement across wide flow ranges for plant sub-metering, energy allocation and internal billing.
Hydrogen & green gas
FMG gas meters certified for hydrogen blends - up to 100% H₂ (without MID) and 20% H₂ (with MID) - alongside Transus Instruments ultrasonic meters up to 40% H₂-ready, future-proofing your infrastructure.
