Abstract
The present disclosure relates to a method for determining fill level of a substance in a container using a measuring device working according to the travel time principle. The measuring device transmits signals to the fill substance and, based on signal fractions reflected back in the container, ascertains an echo curve. The echo curve is transmitted to a superordinate control unit, and an envelope curve enveloping the echo curve is created and transmitted to the superordinate control unit. The echo curve and envelope curve are evaluated by the superordinate control unit. A wanted echo signal of the echo curve and envelope curve is identified. During the determining of the fill level the fill substance and the container are subjected to a current process. Based on information concerning the current process, plausibility of the wanted echo signal is checked and the evaluation is dynamically adapted to the current process.
