Abstract
Official abstract text for this publication.
A method which allows especially the extrapolation of the measured value at the upper and lower end of a measuring range where normally no direct measurement range where normally no direct measurement is possible by superposition of interfering signals, for example by reflection on a radar antenna. In the presence of strong interference signals, for example by reflection of a radar antenna. In the presence of strong interference signals, which are for example caused by the natural resonance of the container or neck in which the measuring device is mounted, the direct level indicator signal can be regularly used if it has a high amplitude caused by a superposition with the interfering signal lies between two interfering signals and does not extend beyond these, the level indicator value can be interpolated by the shift of the signals from the point of reflection. The inventive method automatically adapts itself to a prevailing measuring situation while according to known methods for the user has to decide between a measurement via a shift of EOL signal or a measurement via the direct level indicator echo.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for evaluating measurement signals of a measurement curve of a fill level measurement device operating on a travel time principle and serving for measuring the fill level of a medium in a container, which method comprises the steps of: using the fill level measurement device operating on a travel time principle to perform the steps of: obtaining reference signals data as a function of the travel time of the signals, whereby the reference si…
