Abstract
A method and apparatus for determining the flow rate and other flow characteristics of a polyphase fluid or a turbulent single-phase fluid flowing in a conduit are disclosed. Two differential pressure sensors are provided, each having two pressure ports sensitive to local pressure variation in the fluid. The pressure ports are maintained in a predetermined spatial relationship and in a predetermined orientation relative to the general direction of the flow. The detection signals from the respective sensors are correlated to obtain the flow rate. Additionally, a selected one of the detection signals is processed to obtain other flow characteristics. One of these other flow characteristics, the type of flow, is useful in facilitating the determination of the flow rate.
