METHOD AND DEVICE FOR DETERMINING THE LEVEL OF A LIQUID IN A CONTAINER

摘要

The invention relates to a method and to a device for determining the level of a liquid in a container. The aim of the invention is to provide a reliable indication at the critical levels. To this end, the level in the container (10) is no longer continuously measured across the entire range. The electrodes (141, 142, 143) for level measurement are configured in such a way that the measurement value sharply changes when certain limits of the level are exceeded or fallen short of. These leaps of the measurement values can be reliably recognized without high demands on the accuracy of measurement. The limits are for logical reasons the conditions container full (FS2), container at minimum level (FS3) and "container empty" (FS4).
