Supplementary comparison of gravimetric standards for hydrogen refuelling stations

Project Description

The aim of this comparison is to validate existing gravimetric standards used for calibrating hydrogen refueling stations (HRS) and allow the participants to declare CMCs for this new quantity.
A Coriolis meter will be mounted in the HRS and serve as transfer standard.

The comparison has not started yet. The initial plan was to use a HRS station in Switzerland (EMPA), but the consortium has waited almost two years for the hydrogen refueling station to be operational. Finally, we have decided to go to another location in Germany (ZBT). The measurements are expected to start week 12 for CESAME EXADEBIT and week 13 for METAS.
