Abstract
A method for ascertaining and monitoring fill level of a medium in a container using a travel time measuring method, wherein transmission signals are transmitted toward the medium and reflection signals are received. The received reflection signals are registered as echo signals in an echo function dependent on travel time. Based on known measuring device- and container-specific reflection planes, possible reflection regions in the echo function are calculated by means of an evaluation algorithm. In the calculated reflection regions, the disturbance echo signals and/or the multiecho signals in the echo function are classified, wherein non-classified reflection signals are ascertained and checked as wanted echo signals by means of a search algorithm, wherein, from a position and/or an amplitude of at least one wanted echo signal, fill level is determined, and wherein the measured value of fill level is output.
