Abstract
A filling level measuring device for the microwave-based determination of the filling level of a filling material in a container includes at least one reflection point arranged outside the container. The reflection point generates a reflection point echo signal by means of reflection of a transmit signal, wherein an electronics unit calibrates and/or verifies a filling material echo signal in-line based upon the at least one reflection point echo signal. Further disclosed is a method for the in-line calibration and/or verification of a filling level measuring device.
