Can Goldcard gas meters measure hydrogen-blended natural gas?

Goldcard’s Ultrasonic Smart Gas Meter is specified for gas groups H, L, and E, including gas mixtures containing up to 23% hydrogen, according to the product brochure.

For industrial applications, the TUS ultrasonic gas flowmeter supports natural gas, air, and other special gases. Certain explosion-proof configurations are certified for gas groups marked IIB + H₂.

Hydrogen compatibility should not be determined only by the hydrogen percentage. The application must also be evaluated according to operating pressure, temperature, sealing materials, meter configuration, explosion-proof requirements, and local standards.
