AW-Lake - Model TCMH 0450 -High Pressure Hydrogen Coriolis Mass Flow Meter

SHARE

The TCMH 0450 High Pressure Hydrogen Coriolis Mass Flow Meter is the world’s first MI-002 / OIML137 certified Coriolis flow meter for hydrogen dispensing and is offered in three pressure ratings: 6,000 psi, 10,000 psi and 15,200 psi. The U-shape tubes are made from Sandvik® Alloy HP 160, chosen to eliminate hydrogen embrittlement, such as in Hydrogen fueling stations.
