A LEVEL MEASUREMENT SYSTEM FOR CONDUCTIVE LIQUIDS

摘要

The present invention relates to a level measurement system for conductive liquids including a liquid container (10) and at least three electrodes (18, 20, 22) arranged inside the liquid container (10) at different levels. The electrodes (18, 20, 22) are connected to a network comprising a plurality of resistor elements (R, R1, R2, R3, RP1, RP2, RR1, RR2). The network comprises at least two input terminals (V+, GND) for applying an external voltage. The network comprises at least two output terminals providing a voltage depending on the level of the conductive liquid in the liquid container (10). The level measurement system is provided for detecting at least three different levels of conductive liquids in the liquid container (10) and indicating said levels by one voltage value. In particular, the present invention relates to a level measurement system for water in a storage container. Further, the present invention relates to a domestic appliance comprising at least one liquid container for supplying said domestic appliance with liquid.
