Magnetostrictive Level measurementwith ring magnetwith bar magnets
A ferromagnetic wire is penetrated simultaneously by a local longitudinal magnetic field from the float magnet and a circular magnetic field generated by a current pulse, which interferes at the position of the float magnet. This causes the Wiedemann-effect i.e. a striction onto the wire, which travels as a torsional wave along the wire with a specific sonic speed. The position of the magnet is determined precisely by measuring the runtime, which is directly proportional to the liquid level.
