A numerical study of the flow of an electrically conductive fluid is carried out in a cell under the action of a constant magnetic field. Distribution of electromotive force is investigated as well as the topology of electric current in the cell. The evolutions of velocity field are studied for different parameters. Two large scale unstable eddies are generated in the cell. The characteristic of the flow oscillations are determined using the wavelet analysis. It was found that an increase of current does not lead to the appearance of additional oscillation modes. Asymmetric pressure distribution may appear in the cell. Particle movement are possible due to the asymmetric pressure field.

The paper presents the developed electromagnetic non-invasive level and electrical conductivity sensors for non-ferrous and alkali metals. The influence of the geometry of the installations on the measurement accuracy was experimentally determined. The limits of permissible errors in the positioning of the sensors relative to the analyzed volumes of metals are established.
