The TCMH 0450 High Pressure TRICOR Coriolis flowmeter (photo) is said to be the world’s first MI-002 /OIML137-certified Coriolis flowmeter for hydrogen dispensing applications. By securing this certification, the TCMH 0450 can now be used in custody-transfer applications — specifically in H2 dispensing stations for the fast-growing H2 -powered vehicle market. By using the TCMH 0450 flowmeter, companies can sell H2 fuel to end users with taxation. Without a certified fuel dispenser, the taxation of H2 is not possible. Because H2 is so light, flowmeters in hydrogen dispensers must operate at high pressures (up to 1,050 bars), and tolerate extreme and rapid temperature changes. — KEM Küppers Elektromechanik GmbH, Karlsfeld, Germany
