摘要： A multiphase flow meter (MPFM) for determining component flowrates of multiple component phases within a multiphase mixture having a multiphase flowrate is disclosed. The MPFM may include a first venturi having a first constriction diameter; a second venturi having a second constriction diameter; a gamma ray tomograph fluidly connected to the first venturi and the second venturi; and a tomography controller communicably connected to the gamma ray tomograph. The tomography controller may be configured to calculate a first venturi multiphase flowrate using a first pressure change sensed across the first venturi and a second venturi multiphase flowrate using a second pressure change sensed across the second venturi. Additionally, the tomography controller may be configured to determine the component flowrates of the multiple component phases using a multiphase flowrate calculated from the first venturi multiphase flowrate and the second venturi multiphase flowrate.
