Final Report, 1 March 2000
The full final report "An Inter-comparison of Bell Prover Facilities at Twelve European Laboratories Using a Rotary Gas Meter" is available for download.
A positive displacement meter will be used to compare Bell Provers over the flow range 0.4 -
The laboratories should carry out the calibration using their normal procedures. If laboratories are not able to cover all the flowrates they may calibrate the meter over part of the flow range.
The intercomparison will provide details of international facility agreement.
