An electromagnetic device for measurement of components of flow velocity vector of electroconductive liquid includes a cylindrical strong non-magnetic body with elongated shape with given ratio of length and diameter. In the body with possibility of rotation with respect to its axis magnetic block is installed, this is formed of at least two pairs of permanent magnets with alternating polarity. The magnets are oriented in such way that magnetic field is directed along the axis of rotation of magnetic block. On each of the magnets on its poles tips made of magnetic material are fixed, the free ends of those form a zone of concentration of magnetic field. On the body, at the middle of its length, at least two pairs of electrodes placed in liquid and connected to electronic block are fixed, the working surfaces of those are in the zone of concentration of magnetic field at given distance from the free ends of the tips. |
