Abstract
A method and an apparatus for monitoring a set fill level of a medium in a container using a fill level measuring probe that is designed to operate as a conductive fill level measuring probe in a conductive operating mode and as a capacitive fill level measuring probe in a capacitive operating mode, with a control/evaluation/output unit that is designed to alternately trigger conductive operating mode and capacitive operating mode, and with a control/evaluation/output unit that determines whether the set fill level of the medium in the container has been reached on the basis of the measured values from the two operating modes, and which generates a message when the set fill level is exceeded and/or undershot.
