Abstract

A method for determining and/or monitoring a predeterminable fill level of a medium in a containment with a sensor having a sensor unit with a mechanically oscillatable unit in the form of an oscillatory fork and at least one piezoelectric element comprises exciting the sensor unit with an excitation signal such that mechanical oscillations are executed, receiving the mechanical oscillations of the sensor unit and converting such into a first received signal, transmitting a transmitted signal from the sensor unit and receiving a second received signal and ascertaining information concerning the predeterminable fill level of medium in the containment based on the first received signal. Information concerning state of the sensor unit is ascertained based on the second received signal.
