Embodiment Construction

[0078] The illustrations in the figures are schematic and not to scale. exist Figure 1 to Figure 9 In the following description of the , the same reference numerals are used for the same or corresponding elements.

[0079] In all types of distance or fill level measurements, the present invention can be used to determine the position of the filling material surface. The distance to the filling material determined using the evaluation device, method or level gauge can be provided in analog form (eg via a 4...20 mA interface) or also in digital form (eg via a fieldbus). For this purpose, an external interface can be used, via which a further external device can access the characteristic variables of the position of the separation layer or the boundary layer outside the evaluation device. For example, the distance of the separation layer from the level gauge or from the reference surface can be provided. In other words, a given characteristic variable can be communicated to a...

Abstract

The invention describes an evaluation device (701) and a method for determining a characteristic variable (dL) for the position of a boundary surface (105, 108) in a container (109, 501, 601), wherein multiple echoes (207, 209, 405, 611) including at least one stage (N, N1, N2) is identified in the echo curve (204, 427), wherein the characteristic variable (dL) of the boundary surface in the container is determined based on the positions (DML1, DML2, DMB1) of the multiple echoes and the stages (N, N1, N2)of the multiple echoes.
