UNCERTAINTY ANALYSIS IN PISTON PROVER CALIBRATION
Abstract
This paper presents main uncertainties sources, differential equations analysis and the estimation of combined uncertainty in the calibration of a compact piston prover of the IPT Flow Laboratory.<BR />The piston prover is used mainly for calibration of liquid flow meters as turbine meters, positive displacement meters and rotameters. Calibration of other types of liquid flow meters can also be performed provided its particularities are taken into account. <BR />The procedure used was the gravimetric method with static weighing using water (Water Draw) as described in ISO 4185/80 Measurement of liquid flow in closed conduits - weighing method. The uncertainty analysis was made according to the ISO GUM - International Standard Organization - Guide to the Expression of Uncertainty in Measurement.
