Claim Text:
1. An apparatus for determining and/or monitoring at least one fill level of a medium in a container, comprising: a capacitive or conductive probe unit having at least one electrode; and a control/evaluation unit, wherein: said at least one electrode is embodied as a hollow body, with an end region protruding into the container and embodied as an oscillatable membrane, on an inner side of which a driving/receiving unit is arranged, which excites said oscillatable membrane to execute mechanical oscillations and receive mechanical oscillations therefrom and convert such into an electrical, received signal; said control/evaluation unit supplies said at least one electrode at least at times with a voltage and determines the fill level of the medium capacitively or conductively; and/or said the control/evaluation unit supplies said driving/receiving unit at least at times with an exciter signal and determines from the electrical received signal the fill level of the medium.
