Measurement uncertainly evaluation features for well gas-liquid flow structure monitoring

P.M. Rayter
Annotations languages:

At article the measurement uncertainly evaluation technique features for well gas-liquid flow structure and phase flow rate monitoring are presented. The flow structure monitoring practicability for measurement system metrological examination is explained and difficulties hereto related are defined. Multiphase flow basic regimes and flow regime effect to the combined uncertainty determination has been analyzed. Quadrature methods and Monte Carlo Simulation relations have been presented for the uncertainly evaluation.
Keywords: measurement uncertainty, gas-liquid flow, flow regime, flow pattern, quadrature methods, Monte Carlo Simulation
