Gas measuring & monitoring

for gases e.g. natural gas, nitrogen, hydrogen

Regardless of whether recording, controlling or measuring – in the field of gas measurement technology you will find a wide variety of test benches and systems that we have optimized for the field of measurement technology in the field of natural gas and hydrogen. This includes reference gas meters for low-flow measurements, calibration test bench for gas meters in the areas of end-of-line, development or endurance testing and closed-loop or HPPP systems for the overpressure calibration of gas meters. Further details are shown in the table below. In addition, we show two other systems here – the GasPro mobile gas sampler for representative gas sampling to determine the gas quality in the gas network and a Wobbe Control System, a natural gas supply station with a control system for constant calorific value. Our flow measurement technology is therefore specifically tailored to gas technology.

  • Test item measurement and data acquisition evaluation of various gas meter types
  • Measurement technology in Ex areas, etc.
