Abstract

A method for determining the fill level of a medium, wherein a transmission signal is transmitted, a return signal is received, and the return signal is evaluated in view of the process variable in a manner which allows a general and flexible handling of interfering signals in the received signals. This result is obtained by filtering at least one of the return signal, a signal derived from the return signal and an envelope curve formed from the return signal into at least one sub-signal, and using said at least one sub-signal for evaluating the return signal for at least determining the fill level.
