Abstract
The parameters are calculated of a target function which describes the relationship of the positions of two different tracks. Using this target function, the position of another track can then be derived from the position of one track.
Claims12
A filling level measuring device, comprising:
- an echo curve detection unit detecting a plurality of temporally successive echo curves;
- and
- an evaluation unit configured to:
- determine a first echo and a second echo in each of the echo curves detected, respectively, by evaluating the echo curves, the first echoes being assigned to a first track and the second echoes being assigned to a second track;
- calculate a first functional relationship between the positions of the first track and the positions of the second track of the echo curves;
- the echo curve detection unit being configured to detect an additional echo curve;
- the evaluation unit being further configured to:
- determine the position of a first echo of the additional echo curve by evaluating the additional echo curve, the first echo belonging to the first track;
- calculate the position of the second track at the time of the additional echo curve using the position of the first echo of the additional echo curve, or the position of the first track at the time of the additional echo curve, and the first functional relationship.
