Hydrogen as a Fuel Now Safer with New High-Precision Mass Flow Meter
An open road ahead for the fuel cell: The first high-precision mass flow meter for hydrogen filling stations certified to international standard OIML R 139 2018
March 15, 2021 (FPRC) On the road to climate-friendlier mobility, hydrogen is gaining importance as an energy source for fuel cells. However, fueling of hydrogen is more complex than fueling 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. Therefore, Heinrichs Messtechnik GmbH has developed the TMU-W 004 mass flow meter, which ensures precise metering despite pressure and temperature fluctuations. The device is the first of its kind certified to international standard OIML R 139 2018 and thus approved for hydrogen filling stations. A robust, slender housing protects specially arranged sensors and measuring loops that use the Coriolis
