METHOD AND DEVICE FOR DETECTING AND/OR MONITORING THE LEVEL OF A MEDIUM IN A CONTAINER

摘要

The invention relates to a method and a device for detecting and/or monitoring the level of a medium in a container or for detecting the density of a medium in a container. The aim of the invention is to provide a method and a device which enable the level or the density of a medium to be reliably detected and/or monitored. According to the inventive device, at least one first mode and one second mode of the oscillations of the unit (2) that can oscillate are evaluated and a change in the mass is detected on the unit (2) according to the evaluated modes, whereby said unit can oscillate.
