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.

摘要： A method for determining and or monitoring at least one process- and/or system specific parameter in automation technology. An oscillatable system is provided, which interacts with a medium located in a container, wherein the oscillatable system is excited to oscillate via a real input signal, wherein the real output signal of the oscillatable system is ascertained, wherein the real output signal is digitized and a real output sequence yu(k) is produced. The real input signal is digitized and a digital input sequence (u(k)) is produced, wherein the digital input sequence (u(k)) is fed to a function block (model), which provides at least one mathematical model of the oscillatable system in interaction with the medium. The mathematical model is defined by a number of process- and/or system specific parameters, wherein via the mathematical model a virtual output sequence (ym(k)) is produced, wherein the virtual output sequence ym(k) is compared with the real output sequence yu(k). In the case of a deviation, at least one process- and/or system specific parameter of the mathematical model is adaptively changed, until the deviation between the virtual output signal and the real output signal of the oscillatable unit lies within a predetermined tolerance range and wherein at least one of the process- and/or system specific parameters is provided.
