  • Patent number: 4168624
    Abstract: In accordance with an illustrative embodiment of the present invention, the respective volume flow rates of a gas and a liquid flowing in a conduit are determined by measuring the total volume flowrate, the pressure and the temperature of the two-phase mixture at first and second spaced points in the conduit, creating a pressure drop in the conduit between the first and second points, and determining the respective volume flowrates of the gas and liquid utilizing the measured values of total volume flowrates, pressures and temperatures. The invention has particular utility in well testing.
