Abstract: Since January 2006, the MESURA company, located in FORBACH France, manufacturer of gas regulators for the distribution networks up to 4 bar, has been developing a design which integrates two functions on the same body, thus optimizing the volume (16 cm or 6.3 inch cubic volume), the pressure regulation and flow metering, and in addition, providing wireless data transmission and remote safety control. The evaluation and the qualification of the complete system and the process (including uncertainties) has been undertaken by the French laboratory LNE-LADG in order to confirm the metering of volume gas (converted with a 0.5% level of uncertainty with the global MPE less than 1% with a known density, and less than 2% with an integrated density corrector between the transitional and the maximal flow rate with the metering scale factor up to 150).
