摘要： An improved and more accurate method for evaluating and correcting total measurement signals (TS(n)) of measuring devices. The invention concerns a method for evaluating and correcting total measurement signals (TS(n)) of a measuring device, wherein measuring signals are transmitted in the direction of a medium and reflected on a surface of the medium as wanted echo signals or on a surface of a disturbing element as interference signals and received. In the case of a modification of at least one technical, process condition in the container and/or a modification of at least one technical, measurement condition of the measuring device, an independent reference curve is ascertained on the basis of a current static reference curve, wherein the interference signals are masked out of the raw echo curve on the basis of a masking algorithm, which applies the independent reference curve.

摘要： 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.
