Abstract:
1. A fill-level measuring device for determining a position of at least one of (a) a fill level, (b) a feed material and (c) an interface between two feed materials in a container, wherein fill-level measuring device is configured to emit electromagnetic or acoustic waves in a direction of a feed material surface, comprising: an echo curve acquisition device configured to acquire at least one echo curve based a received signal from the emitted electromagnetic or acoustic waves; an echo identification device configured to identify at least two echoes in the at least one echo curve; and a speed determination device configured to determine speed values of the at least two echoes; wherein the fill-level measuring device is further configured to automatically determine a characteristic value relating to (a) a length of a dome shaft of a dome arranged in an apex region of the container, (b) a container height of the container, (c) a permeability value of a feed material, and/or (d) a permittivity value of a feed material, and wherein the fill-level measuring device is further configured to automatically determine the characteristic value with the use of at least one of the determined speed values of the echoes.
