Abstract (en)
[origin: EP2136188A1] A level sensor (10) particularly for liquids comprising at least two capacitors (12, 13) arranged side by side, to be immersed in the same liquid (14) whose level is to be measured and having the same capacitance (C, C1) when they are immersed in the liquid (14) but a different geometry (S, S1, D, D1), both capacitors being connected to a control unit (15) that is designed to compare the signals that arrive from the two capacitors.
