Abstract
A system and method for monitoring multiphase fluid flow includes a pipe section. The system further includes a plurality of patch antennas including pairs of transmitting antennas and receiving antennas integrated on an exterior surface of the pipe section, each patch antenna having a ground plane. The system further includes an electromagnetic wave generator connected to the patch antennas. The system further includes a phase detector connected to the patch antennas. The system further includes a processing unit configured to determine a relative proportion of constituents in a multiphase fluid flowing through the pipe section based on phase shifts measured by the phase detector.
