Device and method for determining media characteristics and container characteristics

摘要

A fill-level measuring device includes a self-learn device that is able to automatically determine the length of the dome shaft of the container. To this effect the self-learn device uses a multiple echo classified as such by a multiple-echo detection device. In this manner the result of fill level measuring may be improved.

主权项

1. A fill-level measuring device for determining a position of a fill level of at least one of (a) a feed material and (b) an interface between two feed materials in a container using electromagnetic or acoustic waves which are emitted in a direction of a surface of at least one of the feed material and the interface, comprising:
an echo-curve acquisition device configured to acquire at least one echo curve from reflections of the waves; an echo identification device configured to evaluate the at least one echo curve; a multiple-echo detection device configured to classify at least one echo of a multiple reflection from at least one of (a) a feed material surface and (b) a bottom of the container as a multiple echo; and a self-learn device configured to automatically determine a length of a dome shaft of a dome arranged in an apex region of the container with the use of at least two multiple echoes classified by the multiple-echo detection device.
