Abstract

MAGNETIZATION DEVICE FOR A NUCLEAR MAGNETIC FLOW METER A magnetization device for permeation of a multiphase fluid flowing through a measurement tube of a nuclear magnetic flow meter with a magnetic field which is homogenous at least in one plane, with a plurality of permanent magnets for generation of a magnetic field and with a carrier, the carrier having at least one magnet receiver, each magnet receiver accommodating at least one of the permanent magnets, the shape of the magnet receivers and of the permanent magnets allowing movement of the permanent magnets in the magnet receivers only in one direction and the permanent magnets being by the magnet receivers arranged with reference to the magnetic field. A magnetization device with reduced production and time expenditure is achieved by the magnet receivers being made as hollow profiles.
