Abstract
Systems and methods are described for measuring flow properties of a high gas-cut multiphase mixture flowing in a conduit, such as a wet-gas produced from a hydrocarbon well. In aspects of the present invention, one or more receivers are used to receive Doppler shifted signals resulting from an interaction between a propagating dominant microwave mode developed in the conduit and the high gas-cut multiphase mixture flowing in the conduit. Analysis of the Doppler shift in the received signals may provide for determining the velocity of the gas and/or the liquid phase of the high gas-cut multiphase mixture. In other aspects, analysis of the phase difference of Doppler signals received at the plurality of receivers provides for a determination of the content of the wet-gas, such as the water holdup.
