More Information
Summary:Systems and methods are disclosed for measuring densities and flow rates of gas-liquid fluid mixtures. In the systems and methods, the fluid mixture is caused to exhibit swirling flow as it flows through a conduit (1) that includes a constriction (3), a first pressure difference (DeltaP1) is measured between two vertically-spaced measurement positions in the conduit, a second pressure difference (DeltaP2) is measured between two horizontally-spaced measurement positions in the conduit, the first horizontally-spaced measurement position being at the constriction region and the second horizontally-spaced measurement position being upstream or downstream of the constriction region, and one or more of the pressure differences is used to determine a density or a flow rate of the gas-liquid fluid mixture.
