Final report on APMP.M.FF-K2 bilateral comparison: Hydrocarbon liquid flow

This bilateral comparison was carried out in the field of liquid hydrocarbon flow following the Guidelines for CIPM Key Comparisons. This APMP.M.FF-K2 comparison involved two laboratories: Center for Measurement Standards (CMS, Chinese Taipei) and Vietnam Measurement Institute (VMI), which are both national standard calibration laboratories. The bilateral comparison was conducted using light liquid hydrocarbon across a flow range of 5 L s... to 30 L s... A Kral positive displacement meter served as the transfer standard. The Strouhal number and Reynolds number served as the key parameters for expressing the laboratories' measurements of volume and flowrate. The En value of the VMI test results with reference to CMS was 0.28. (ProQuest: ... denotes formulae/symbols omitted.)
