摘要：
The invention relates to a device for determining and/or monitoring the level of a filling material in a container. According to the invention, an oscillatable unit (2) is provided which is fastened to a membrane (5), whereby said oscillatable unit (2) is mounted at the height of the predetermined level. An emitting-receiving unit (6) is provided which, with a given emit frequency, causes the membrane (5) and the oscillatable unit (2) to oscillate, and which receives the oscillations of the oscillatable unit (2). A control/evaluation unit (10) is provided, which identifies once the predetermined level is obtained upon a given change in frequency or which, with the aid of the oscillation frequency of the oscillatable unit (2), determines the density of the filling material.
