Modelling experiments were carried out to demonstrate the feasibility and perspectives of using the contactless inductive rotary permanent magnets' electromagnetic flowmeter to control liquid metal flows. The sensitive element of the flowmeter is a freely rotating magnetic system composed of strong rear earth permanent magnets mounted on the cylindrical- or disk-type ferromagnetic base. The principle of the flowmeter operation is based on the well-known Lorentz force arising at the interaction of a moving electrically conducting medium and an imposed external magnetic field. The angular rotation speed of the magnetic system is proportional to the velocity of liquid metal flow and at the same time shows the direction of the liquid metal flow. Figs 9, Refs 6.
