Abstract

A device for monitoring the level of a liquid in a tank comprises a plurality of thermistors 51,....mounted at different levels and each having different resistance values according to whether it is covered or not covered by the liquid. Changes in resistance values are detected to reset a fuel quantity register R to the corresponding reading. A flowmeter is arranged to decrement the reading between successive such resettings, and a differentiation system D1...D4 takes into account the direction of displacement of the level of the liquid, to index the register R to the correct values.
