Title:
MULTIPHASE FLOW METERING SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/124809
Kind Code:
A1
Abstract:
A multiphase flow metering system, comprising a magnetic resonance multiphase flowmeter (1) and a manifold system, which is correspondingly configured, wherein the manifold system comprises a plurality of control valves and a connection pipeline and is used for controlling a corresponding fluid to flow through the magnetic resonance multiphase flowmeter (1); and the magnetic resonance multiphase flowmeter (1) comprises a plurality of magnet structures, which are distributed at intervals in an axial direction of the magnetic resonance multiphase flowmeter (1) and are used for magnetizing a fluid, and further comprises two measurement antennas, which are distributed at intervals in the axial direction of the magnetic resonance multiphase flowmeter (1) and are used for performing phase state detection on the magnetized fluid. A multiphase flow metering method is implemented on the basis of the multiphase flow metering system, and comprises: according to a selected measurement requirement and by using a corresponding measurement method, measuring a phase state parameter of a fluid, wherein the phase state parameter is a content or speed parameter of a target phase state; simultaneously collecting reflected signals of the fluid by means of two measurement antennas; and reading the phase state parameter of the fluid according to the collected reflected signals and a preset apparatus scale.
