Abstract

A method for filling level measuring includes generating an echo curve. The echo curve is analyzed by at least one analysis method selected from analysis methods including analyzing the echo curve by at least two parallel tasks or is analyzed by comparing the echo curve with a spurious-echo curve at the IF-level.
