FIELD: instrumentation.SUBSTANCE: invention relates to electrical engineering and can be used in nuclear-magnetic flow meters. The magnetiser is meant for piercing by the multiphase fluid flowing through and nuclear-magnetic flow meter measuring tube. Magnetic field, homogeneous in at least one plane, is induced by several permanent magnets with bearing elements. The bearing element has at least one magnetic fastener each being provided with at least one permanent magnet. Profiling of magnetic fasteners composed of hollow sections and permanent magnets allows the displacement of permanent magnets in said magnetic fasteners in one direction only. Permanent magnets secured in magnetic fasteners by are arranged relative to the magnetic field.EFFECT: lower costs, homogeneous magnetic flux.18 cl, 4 dwg |
