ALTOSONIC V12 - Ultrasonic flowmeter for custody transfer (CT) flow measurement of hydrogen and other gases

Krohne Messtechnik GmbH Hall: B7 Stand: 7D45

The ALTOSONIC V12 is a high-performance multipath ultrasonic flowmeter for custody transfer measurement of gases. The meter is designed to deliver high measurement accuracy under both ideal calibration conditions and real field conditions. It supports natural gas, natural gas/hydrogen mixtures, pure hydrogen, CO₂ and many other gases as required by gas Transmission System Operators. Unlike other CT gas flowmeters on the market, the ALTOSONIC V12 features a dedicated center path, significantly improving Reynolds number independence and minimising sensitivity to flow profile distortions. Even with changes in gas composition, accuracy is not compromised, resulting in greater flexibility and reduced calibration costs. Calibration at a single reference gas allows the flowmeter to be used with a wide range of gases and gas compositions. The meter has been extensively tested and fully complies with all ISO and AGA perturbation requirements. This ensures higher measurement reliability, excellent performance, and overall long-term stability.

Fully compliant with AGA, ISO 17089-1, AGA 9, OIML R137 class 0.5, MI-002, etc.

Suitable for various gases - from natural gas via gas mixtures to pure hydrogen

Dedicated diagnostic chords to detect bottom fouling

From DN100 / 4" to max. DN750 / 30"; up to 450 bar / 6,525 psi
