Abstract
A device () measures capacity, and includes an electrode arrangement with a plurality of electrodes (E, E, . . . , En) which are adjacently and/or successively arranged on a carrier (). An intrinsic measuring device () measures the capacitance between a first electrode (E), in the form of a measuring electrode, and a second electrode (E), in the form of a counter-electrode. A controllable switching device () connects the electrodes (E, E, . . . , En), in the form of first and second electrodes (E, E), to the measuring device () in such a way that they can be switched in a pre-determinable manner. Each electrode (E, E, . . . , En) of the electrode arrangement can be switched in a controlled, alternate manner by the switching device (), in the form of a measuring electrode, and respectively at least one of the other electrodes (E, E, . . . , En), in the form of a counter-electrode, can be switched to a pre-determinable reference potential. An associate method and a device () determine the level () of a liquid () using one such device ().
