摘要
Determination of the quantity of liquid product contained in a reservoir, with the help of a capacitive arrangement.;The invention is applicable to a reservoir (112) comprising a compartment (166) where the product is in the captive state, for example impregnating a porous body, and the conductive electrodes (221, 222) associated with this compartment are situated on either side of the volume where the product is in the captive state and offset with respect to one another in order to be located respectively in the vicinity of two opposite ends of this volume.;When the reservoir has another compartment where the product is in the free state, the electrodes of the capacitive arrangement are advantageously L-shaped.
