A method and apparatus for investigating a multi-phase fluid flow

摘要

A method and apparatus for investigating a gas-liquid fluid mixture as it is conveyed in a conduit having a first constriction region providing a reduced conduit cross section. The method includes the steps of: inducing the mixture to exhibit swirling flow in the first constriction region, thereby separating the liquid from the gas; and determining one or more properties of the fluid in the first constriction region. The apparatus includes a measurement assembly for determining one or more properties of the liquid as it flows through the first constriction region.
