"TWO-PHASE FLOWMETER" ABSTRACT OF THE DISCLOSURE The present invention provides a flowmeter for measuring pressure drops indicative of the flowrates of the individual phases in a gas and liquid containing two-phase stream. Means are provided for creating and measuring a frictional pressure drop in the two-phase flow. Means are also provided for creating and measuring an acceleration pres- sure drop in the two-phase flow. Mathematical models are known in two- phase theory for correlating these pressure drop measurements with the flowrates of the individual phases. In a preferred mode of the invention the frictional pressure drop is measured across a twisted tape; the accelerational pressure drop is measured across a venturi downstream of the twisted tape, and the pressure drops are measured by pressure transducer means. The meter also preferably provides means for measuring the static pressure of the two-phase flow.
