Method and device for measuring the debits of the liquid and gaseous phases of a two-phase fluid in 2002

摘要

The invention relates to a method for measuring the debits of the liquid and gaseous phases of a two-phase fluid in 2002. / p & & p & it is set in rotation the two-phase fluid around a longitudinal axis of a generation of a coaxial discharge having a tubular layer 15 formed of the gaseous phase surrounded by a tubular layer 16 formed of the liquid phase, that is measured downstream of the zone where the two-phase fluid has been set in rotation on the one hand, the thicknesses of the tubular layers of the liquid phase and gaseous phase and the other hand, the rate of discharge of at least the liquid phase v and that from the values measured of thickness and in velocity will determine by comparison of the detected models mathematics and or the debits the volume and mass of each phase and the volumetric ratio of the gaseous phase and the liquid phase in the thermodynamic conditions of the two-phase fluid.
