Calibration Facility at TwinLoop

High-pressure test benches for hydrogen and natural gas

For many years already, we have been successfully calibrating, adjusting and verifying gas meters for natural gas. We are a state-approved testing center (GBW 12) for gas meters. Now, we have added the H2-Loop to our product portfolio. Both high-pressure test benches, the H2-Loop and the natural gas loop, are now located opposite each other in our factory building in Rheinau, Germany and building our Calibration Facility.

Both volumetric gas meters (rotary gas meters) and flow gas meters (ultrasonic gas meters, vortex gas meters and turbine gas meters) can be tested with our two systems at our test facility. Sophisticated measurements, also in the context of product development or type testing, can be carried out nearly simultanousely.
