H2FlowTrace was presented at the CEN/TC 237 Gas Meters Plenary Meeting 2025, organised by the European Committee of Standarisation (CEN). As last year, the project took a spot in this event, showing our commitment to taking relevant feedback from this committee and providing inputs to update relevant standards to trace hydrogen flow measurement in gas networks traceable to the SI-units of measurement.
The H2FlowTrace project stands out as a vital initiative aiming to fill the gap in traceable hydrogen flow measurement and support the development of harmonised European standards, particularly in direct relation to CEN/TC 237. Regarding this approach, the project has developed a hydrogen calibration programme for different types of meters, such as diaphragm meters (EN 1359:2017), domestic thermal mass meters (EN 17526:2021+A1:2025), as well as ultrasonic domestic gas meters (EN 14236:2018).
Standardisation of gas flow meters is critical for ensuring accuracy, safety, reliability, and interoperability across industrial, commercial, and domestic applications. The H2FlowTrace project stands out as a vital initiative aiming to fill the gap in traceable hydrogen flow measurement and support the development of harmonised European standards. What’s more, our participation in this type of event confirms the importance of the results we are obtaining in H2FlowTrace, as these results are considered by leading standardisation bodies such as CEN.
