The aim of the bilateral-comparison between the NMi Netherlands and METAS Switzerland is to compare the calibration facilities of gas meters by means of calibration of 2 transfer standards in the flow rate range of (0.5 - 1000) m³/h. The transfer standards are Rotary Piston Meter G40 and G650. The laboratories will cover the flow rates using several calibration facilities in order to compare them between the 2 participating laboratories and to compare the different types of calibration facilities of the laboratories.
Final Report 2019-04-11
The meters used in the context of this project are currently used as internal master meters. Therefore we are not able to send it over to other NMIs.
