MAGNETIZATION DEVICE FOR NUCLEAR MAGNETIC FLOWMETER

PROBLEM TO BE SOLVED: To provide a magnetization device which has a sufficiently uniform measurement tube through which fluid flows, and reduces a manufacturing cost and manufacturing time.SOLUTION: A multi-phase fluid flowing through the measurement tube of a nuclear magnetic resonance flowmeter penetrates the magnetization device. The magnetization device has, on at least one surface, a uniform magnetic field, a plurality of permanent magnets forming the magnetic field, and a carrier. The carrier has at least one magnet receiving part each of which receives at least one permanent magnet of the plurality of permanent magnets. The permanent magnet can move in only one direction in the magnet receiving part by the shape of the magnet receiving part and the shape of the permanent magnet. The permanent magnet received in the magnet receiving part is arranged based on the magnetic field by the magnet receiving part. In the magnetization device, the magnet receiving part is formed as a hollow molding.
