Abstract:
1. A method for ascertaining and/or evaluating a fill-state of a container filled with at least one medium, comprising the steps of: emitting high-frequency, electromagnetic, measuring signals from a fill-level measuring device and receiving back by the fill-level measuring device as useful echos reflected at least on an upper surface, at least on an interface of media and/or on at least one separating-layer between media; receiving back the electromagnetic, measuring signals as an end echo reflected at a measuring range end; forming an echo curve dependent on travel-time and/or travel-distance at least from the received useful echos and the end echo; ascertaining by means of a search algorithm integrated in a memory unit in the fill-level measuring device, number, existence and/or position of individual useful echos and end echo in the echo curve, which are applied for classifying a currently present fill-state in the container relative to predetermined, stored, fill situations in the container; and based on said classified currently present fill-state in the container a distance value of a fill-level and/or a distance value of a separating-layer are/is associated with travel-times and/or with travel-distances of individual useful echos and/or the end echo in the echo curve, wherein: the fill situations in the container are given by the search algorithm as partially filled with a first medium or a second medium, filled full with the first medium and/or the second medium, or empty.
