Abstract
A method for ascertaining and/or evaluating the fill-state of a container filled with at least one medium, wherein high-frequency, electromagnetic, measuring signals are emitted by a fill-level measuring device and received back as wanted echos reflected at an interface of the media. The electromagnetic, measuring signals are received back as an end echo reflected at a measuring range end, wherein, from the received wanted echos and the end echo, an echo curve is formed as a function of travel-time and/or the travel-distance, wherein, by means of a search algorithm integrated in the fill-level measuring device, number, existence and/or position of individual wanted echos and of the end echo in the echo curve are/is ascertained and applied for classifying the currently present fill-state in the container relative to predetermined, stored, fill situations in the container. On the basis of the classified fill situation in the container, with a distance value of the fill-level and/or a distance value of the separating-layer are/is associated belonging travel-times and/or belonging travel-distances of the individual wanted echos and/or end echo in the echo curve.
