Meter modules measure multiple gases

It means no meter replacement nor any firmware update will be required for meters that feature the SGM64xx product line when natural gas is gradually or fully substituted with hydrogen.

Since replacing even a small fraction of meters currently in use is significantly more expensive than installing multi-gas capable meters today, utility companies can rest easy and cut future costs significantly.

Carbon neutrality, sustainability and the reduction of CO₂ emissions are the main global trends in the energy sector. Our current gas infrastructure must be prepared for the arrival of renewable gases. In one example, starting in 2025, all new gas boilers installed in the UK will have to be compatible with pure hydrogen. Similar requirements for gas meters are expected to follow shortly after. With SGM64xx, meters will be ready for whatever the future holds.

The SGM64xx is based on the proven and reliable SGM63xx platform, and brings it to a new level by extending its measurement capabilities to pure hydrogen. This is achieved via an augmented calibration procedure, which otherwise does not introduce any changes to the product’s mechanical, electrical and software interfaces.

Furthermore, the hydrogen flow ranges supported by SGM64xx are three-times higher than those of natural gas, which guarantees a compact meter size no matter the hydrogen content.

Gas meters incorporating thermal-mass modules are the best choice for the transition towards a sustainable future. Sensirion’s gas meter modules provide excellent measurement performance and robustness at ultra-low power consumption levels. Therefore, they are suitable for residential and industrial applications covering flow ranges from G1.6 to G25.
