High-precision mass flowmeter for hydrogen filling stations

news item image
On the road to climate-friendlier mobility, hydrogen is gaining importance as an energy source for fuel cells.
However, fuelling of hydrogen is more complex than fuelling of petrol and diesel.
Unlike other gases, hydrogen heats up as it expands, causing pressure and temperature changes during fuelling that need to be precisely monitored.
Heinrichs Messtechnik has developed the TMU-W 004 mass flowmeter, 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 effect and enable very precise flow measurement.
The attached transducer converts the sensor signals into a reading that can be used to further analyse the flow rate.
At the same time the meter measures the temperature of the medium.
The TMU-W 004 is suitable for high-pressure applications up to 1000 bar. This newly developed device is already in use at filling stations of the listed company Nel...
