  • Evaluation of the uncertainty of gas flow measurements by a clearance-sealed piston prover [Elektronski vir]
    Bobovnik, Gregor ; Kutin, Jože ; Bajsič, Ivan
    A piston prover measures the flow rate by determining the time interval that a piston needs to pass a known volume of gas at a defined pressure and a temperature. The evaluation of the calibration ... and measurement capabilities of the clearance-sealed realization of the piston prover is presented. A systematic analysis of the uncertainty covers the components due to the gas density, dimensional and time measurements, the leakage flow, the density correction factor and the repeatability.
