- Abstract:
- 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.
