Flow measurement of pure hydrogen as well as hydrogen-natural gas mixtures

Ultrasonic flowmeter for custody transfer (CT) measurement of gases

The ALTOSONIC V12 is a 12-chord ultrasonic custody transfer (CT) flowmeter for pure hydrogen, natural gas and blends of hydrogen with natural gas. KROHNE offers a wide range of ultrasonic transducer materials for example an epoxy based version. This type of transducer is perfect for hydrogen applications as it has excellent acoustic properties and is not prone to hydrogen embrittlement at high temperatures compared to titanium transducers. Furthermore, the gas flowmeter comes with enhanced diagnostics. Among others, it features a vertical diagnostic path that detects contamination on the bottom of the measuring tube (bottom-fouling detection). In this way, it gives a precise view into the flowmeter, allowing the client to carry out predictive maintenance.

Using the Reynolds flow profile principle, the meter can be calibrated in a natural gas calibration facility at exactly the same flow profiles that will be see in a hydrogen application. The flowmeter is normally calibrated at six flow rates and is certified to MID-002.
