A venturi-assisted flow meter arrangement is disclosed. The venturi is positioned in a pipe or conduit containing the fluid mixture to be measured upstream of the flow meter. The flow meter is preferably a flow rate meter and/or a phase fraction meter. When the fluid mixture is passed through the venturi, it is homogenized or mixed, which can increase the accuracy of the measurements made by the downstream flow meter. Additionally, the venturi can be used to compute the flow momentum of the fluid mixture, which may be used to calibrate or double check the operation of the flow meter, or allow it to compute the phase fraction for a three phase mixture. |
