METHOD AND DEVICE FOR DETERMINING THE FILLING LEVEL IN CONTAINERS

摘要

In order to determine the filling level in containers, mechanical vibrations are generated in the wall of a container (30) and the course of said vibrations is analyzed. The wall of a container in which the vibration is produced is touched at a different distance according to filling level. The vibration pattern is subsequently evaluated according to the distance at which the inside of the container wall (30) is touched. It is thus possible to determine the relaxation time, frequency, intensity and/or the time integral of the intensity or the point of maximum intensity of the mechanical vibrations in the container wall.
