With 70 years of high-pressure innovation and a strong reputation for quality, safety, reliability and expertise in high-pressure liquid and gas transfer and pressurization technology, Haskel manufacture a full range of hydrogen handling equipment.
For typical hydrogen refuelling stations, medium- and high-pressure storage tanks, with pressure stages of 200 to 450 bar and 800 to 1,000 bar respectively, are used to refuel the customer vehicle. The hydrogen from the low-pressure storage tank can be transferred via a high-pressure compressor to the high-pressure storage tank. The pressure there is high enough to directly refuel the vehicle.
As the hydrogen is transferred to storage and into fuel cell vehicles at very high pressures (900 bar), high velocities and at varying temperatures. The provision of a flow meter to measure under these conditions is not a trivial matter as it must be accurate, reliable and suitable for end user point-of-sale billing. Rheonik mass flow meters have proven to be, and continue to be, the most reliable meters for H2 measurement available. Consequently, Rheonik’s RHM04 was supplied and is currently the only mass flow meter that can meet the necessary criteria. This is underlined by Rheonik being the first Coriolis manufacturer to obtain a custody transfer approval for a broad range of mass flowmeters for mobile and stationary hydrogen applications up to 1070 bar according to MID MI002 / OIML R137.
