| description | The invention relates to determining a concentration of magnetic particles in a stream of fluid mixed with the particles through an elongate circumferential enclosure at an axial measurement location along the stream. Use is made of a coil with multiple electrically conducting windings arranged to each tangentially surround the stream at the axial measurement location, for generating a magnetizing field which extends with a radially inwards part thereof inside the stream and with a radially outwards part thereof outside the stream, and of a sensor configured for producing a signal indicative of a magnetic flux density caused by the magnetizing field generated around the coil and/or a change therein. An electromagnetic permeability in the magnetizing field is increased in in the radially inwards part of the magnetizing field by a particle directing tool directing the particles in the stream radially outwardly towards an inner circumference of the coil, and/or in the radially outwards portion of the magnetizing field, by magnetically conducting elements extending along a path around the coil windings so as to guide field lines of the magnetizing field therethrough. |
