Hydrogen is gaining importance as an energy source for fuel cells. However, fuelling of hydrogen is much more complex than fuelling of gasoline and diesel. Unlike other gases, hydrogen heats up as it expands, causing pressure and temperature changes during fuelling that need to be precisely monitored. In response, Kobold’s Heinrichs factory developed the TMU-W004 mass flow meter which ensures precise metering despite pressure and temperature fluctuations.
Certified to International Standard OIML R 139 2018
The device is the first of its kind certified to international standard OIML R 139 2018 and therefore approved for hydrogen filling stations.
