FIELD: measuring technique.
SUBSTANCE: fuel level meter comprises elongated capacitive sensor connected in the frequency-generating circuits of functional and base self excited oscillators. The main and additional counters generate the position code of the fuel level from the output frequencies of the self-excited oscillators. The level is indicated by the linear or pointer indicator provided with a converter of position code into the current of supplied to the pointer indicator.
EFFECT: reduced power consumption and enhanced reliability.
