High Pressure Coriolis for Hydrogen Applications TMU-W
The TMU-W Coriolis mass flow meter by Heinrichs Messtechnik GmbH is the first of its kind to achieve OIML R139:2018 certification “Organization International de Métrologie Légale” in terms of measuring accuracy at high pressure. Therefore, our extensive experience in developing and manufacturing high-precision measurement instruments underpins our knowledge, guaranteeing this meter’s unparalleled measuring accuracy at high pressures and its ability to tackle the unique challenges presented by hydrogen. Designed for high-pressure hydrogen applications, especially for vehicle fuelling stations, the TMU-W sets a new standard in the industry.
With the automotive fuelling sector in mind, we developed the TMU-W series of products. This multipurpose product has other potential uses in other domains as well. Its main characteristics consist of:
• Impressive precision
• Robustness against vibrations
• Versatility in installation positions
• Compact design with a fully welded stainless-steel housing
• Operating pressure over 1000 bar
• OIML R139:2018 approval
• Compliance with SAE J2601 for hydrogen refuelling stations
