MEASURING METHOD AND DEVICE FOR THE LIQUID AND GASEOUS FLOWS OF A TWO PHASED FLOWING FLUID

摘要

specific disclosure.process and apparatus for measuring flow ratethe gas and liquid phases in a two-phase fluidflow. depending on the process fluid is put in rotationin a two-phase longitudinal axis so as to generatea coaxial flow tube having a layer formedthe gas phase surrounded by a tubular layer formedthe liquid phase is measured, and the area where the downstreamtwo-phase fluid has been rotated, on the one hand, thethicknesses of the layers and a liquid phase, and (e)the gas phase and, on the other hand, the velocity of flow atthe liquid phase (vl). on the basis of the measured valuesthickness and velocity is determined from relationshipsdetermined mathematically or experimentally knownthe volumetric ratio of the liquid phase and thethe gas phase, the thickness of the liquid layer, velocitythe fluid flow and axial flow, the volume andthe mass of each stage, and the volumetric ratioin the gas phase and the liquid phase in thethe thermodynamic conditions of two-phase fluid.
