Abstract: A multiphase flow metering system, comprising a magnetic resonance multiphase flowmeter and a manifold system, comprising a plurality of control valves and a connection pipeline, for controlling a fluid to flow through the magnetic resonance multiphase flowmeter; and the magnetic resonance multiphase flowmeter comprising a plurality of magnet structures, distributed at intervals in an axial direction and are configured to magnetize a fluid, and further comprises two measurement antennas, distributed at intervals in the axial direction and are configured to perform phase state detection on the magnetized fluid. A multiphase flow metering method is implemented with the multiphase flow metering system, and comprises: measuring a phase state parameter of a fluid, the phase state parameter being a content or speed parameter of a target phase state; collecting reflected signals of the fluid using two measurement antennas; and reading the phase state parameter of the fluid according to collected reflected signals.
