Abstract
A fill level measuring device for measuring a fill level of a fill substance in a container and a method for fill level measurement using this fill level measuring device are provided. The fill level measuring device can perform fill level measurements upon re-start immediately on its own and reliably, and includes: at least one antenna, which issues transmitted signals (S) and receives echo signals (E); a signal processor, which serves for deriving from the received echo signals (E) an echo function containing the amplitudes (A) of the echo signals (E) as a function of travel time; a memory for storing data in a table whose columns serve for storing the echo functions in the columns in a sequence which corresponds to the fill levels associated with the individual echo functions; and an evaluation unit, which accesses the table for determining the fill level.
