Abstract
A method of determining the level of a medium in a container by generating a constant magnetic field in the container, exciting an elongated sensor element to longitudinal oscillations, the sensor element being secured on one end in the container and containing a magnetostrictive material, measuring the resonant frequency of the sensor element, or the damping of the longitudinal oscillation, by means of periodically varying magnetization of the sensor element in the constant magnetic field, and determining the fill level from the resonant frequency or from the damping of the longitudinal oscillations.
