Metrological investigation particularities for flow structure monitoring and phase gas-liquid well flow rate measuring unseparation system

P.M. Rayter, L.A. Vytvytska
Annotations languages:

Measurement method and developed flow structure monitoring and phase gas-liquid well flow rate measuring unseparation system construction particularities are offered in article. Valuation system’s metrological parameters necessity are proved and conjugate problem with this are defined. System metrological investigation are executed by means summary uncertainty budget creation. Instrumental component uncertainty calculation procedure is produced. Instrumental summary uncertainty value is estimated in terms of prototype model measuring system experimental evidences.
Keywords: measurement uncertainty, gas-liquid flow, phase velocity, wavelet decomposition, liquid hold-up, instrumental component uncertainty, unseparation testing, flow pattern, water-cut
