Abstract
A method for measuring fill level of a fill substance. Transmission signals are sent and their fractions reflected on reflectors in the container and received as received signals. Based on the received, echo functions are derived and wanted echos of predetermined wanted echo types respectively contained in the echo functions and identifiable based on predetermined echo recognition methods are ascertained. Each wanted echo is a local maximum and is attributable to a reflection on a reflector associated with its wanted echo type. Echo quality of each wanted echo is determined. The echo quality is higher, the more peak shaped the echo function is in the region of the respective wanted echo, and the fill level is determined taking into consideration echo qualities of the wanted echos.
