ABSTRACT:
A device for measuring the relative proportions of gas, oil and water in a conductive pipe includes at least one open-ended, conductive tube having a radius different from the pipe, disposed within the pipe. Microwave transmission structure transmits microwave signals along the pipe and the at least one tube at a plurality of frequencies, the pipe and the at least one conductive tube acting as waveguides for the microwave signals. At least two microwave receiving devices are disposed at separate positions having different respective radii, spaced apart along the pipe and at least one tube, for receiving the microwave signals transmitted by the transmission structure. Determining circuitry determines the relative proportions of gas, water and oil in the pipe by comparing the transmitted and received signals.
