Abstract

A method for determining a phase composition of a multiphase mixture flowing through a pipe is presented. The method includes exciting one or more patch antennas configured to operate over the range of frequencies. Further, the method includes acquiring at least one of a transmitted signal and a reflected signal over the range of frequencies from the one or more patch antennas. Moreover, the method includes estimating the phase composition of the multiphase mixture based on a group delay determined from at least one of the transmitted signal and the reflected signal. A system for determining a phase composition of a multiphase mixture flowing through a pipe is also presented.
