Abstract

A transit-time fill-level measuring device for measuring the fill level of a filling material in a container is stated, in which transit-time fill-level measuring device information about the topography of the filling material surface is determined on the basis of the shape of a single echo curve of the receiving signal. From this the fill volume can then be derived.
