Abstract
A method for determining and/or monitoring a predeterminable fill level of a medium in a container using a vibronic sensor having at least one sensor unit with a mechanically vibratable unit, comprises exciting the mechanically vibratable unit with an excitation signal to produce mechanical vibrations, and receiving the mechanical vibrations in the form of a reception signal, determining an amplitude and a frequency of the reception signal, comparing the frequency and amplitude of the reception signal with a predeterminable frequency limit value and a predeterminable amplitude limit value, and determining a reaching of the predeterminable fill level on the basis of the comparison.
