A homogenization device for homogenization of a magnetic field with an non-magnetic carrier and compensation elements formed of a magnetic material, the carrier having a carrier wall and the carrier wall surrounding a carrier interior, in the homogenization device located in the magnetic field the magnetic field penetrating into the carrier interior through a first carrier region of the carrier wall and emerging from the carrier interior through a second carrier region of the carrier wall and each of the compensation elements which are located on the carrier contributing to the homogenization of the magnetic field at least in the carrier interior. In the homogenization device, handling during homogenization is improved in that there are recesses in the carrier wall and in each of the recesses at least one of the compensation elements can be directly inserted and removed.

Homogenization device for homogenization of a magnetic field

A nuclear magnetic flowmeter is disclosed. The nuclear magnetic flowmeter includes a magnetization device located around a straight measuring tube for producing a magnetic field in a medium. The flowmeter also includes a gradient coil that produces a gradient in the field. The flowmeter further includes a signal coil that excites the medium and that detects the result of the excitation. Additionally, the flowmeter includes a coil insulating frame and a sealed housing. The housing is along a longitudinal axis of the tube and has a first face side and a second face side having openings through which the tube is routed. The magnetization device is provided in the interior of the housing. The gradient coil and the signal coil are located in a space between the tube and magnetization device that is penetrated by the field. The gradient coil and/or the signal coil are located on the frame.

Nuclear magnetic flowmeter

A magnetization device with a magnetic field which is generated by permanent magnets for variable magnetization of a medium flowing through a tube over a magnetization distance along the longitudinal axis of the tube. The magnetization device improves the quality of the results relative to known nuclear magnetic resonance measurement and analysis methods in that the magnetic field in the medium has a single direction over the magnetization distance.

A magnet module for a nuclear magnetic flow meter including at least one permanent magnet and a jacket. The jacket protects the at least one permanent magnet against peeling of magnet material by mechanical loads when the magnet module is introduced into a magnet receiver of the flow meter, simplifies introduction of the permanent magnets into the magnet receivers by reduced friction between the magnet module and the magnet receivers, and influences the magnetic field which generated by the permanent magnets.
