The aim of the comparison is to compare high-pressure gas-flow facilities using natural gas and nitrogen. The use of two transfer standards, turbine and Venturi tube, will be used. Proposed flow range is 100 m3/hr to 1600 m3/hr and pressure range from 10 bar to 50 bar.
Progress Report 2019-07-08
Draft protocol has been produced. Project on hold as pilot laboratory has changed traceability links and needs to establish performance and realistic uncertainties including drift from using new reference meters before commencing intercomparison.
Once confidence in new reference meters and traceability chain is well establised, then the protocol will be finalised and the intercomparison will commence.
