  • Dual-beam multiphase fluid analysis systems and methods
    Patent number: 11150203
    Abstract: A method for analyzing flow of a multiphase fluid through a flowmeter is provided. In one embodiment, the method includes transmitting two beams of electromagnetic radiation along different paths through a multiphase fluid and detecting the two transmitted beams with detectors. The method also includes determining a gas fraction and a water-in-liquid ratio of the multiphase fluid. The gas fraction is determined based on the detected first beam of electromagnetic radiation and the water-in-liquid ratio of the multiphase fluid is determined based on the detected second beam of electromagnetic radiation. Additional systems, devices, and methods are also disclosed.
