摘要： The invention relates to a method for the highly accurate determination of the filling level (q) of a product (4) in a container (2), measuring signals being transmitted in the direction of the surface (5) of the filled product (4) and reflected at the surface (5) as echo signals and the filling level (q) in the container (2) being determined by evaluation of the amplitude values (A) and phase values (&psgr;) of the reflected echo signals by means of a pulse delay-time method. Furthermore, an apparatus suitable for carrying out the method is proposed. The invention is based on the object of proposing a method and an apparatus which permit highly accurate filling level measurements in containers (2), even if multipath propagation or multimode propagation occurs. The object is achieved by compensating for errors which occur in the determination of the filling level (q) and are caused by interference signals which interfere constructively or destructively with the echo signals reflected regularly at the surface (5) of the filled product (4).

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.
