Method and device for measuring the properties of a multiphase stream

摘要

A device and method for measuring multiphase flow in a pipeline, comprising an electric measurement system which includes a plurality of capacitors, which capacitors are formed of at least two plates of non-conducting material, each plate being provided with an array of electrodes. The plates are arranged in the interior of the pipeline and extend substantially parallel in the longitudinal direction thereof. The liquid and gas flowrates are gauged by continuously measuring both the velocity and cross-sectional area of the pipeline occupied by each phase. The apparatus may include a correlator for velocity measurement and a computational system. IMAGE
