Abstract
Determination of the quantities of products contained in reservoirs grouped together next to one another by using a capacitive arrangement associated with these reservoirs. According to the invention, electrodes of the capacitive arrangement (121a, 122a-121b, 122b-121c, 122c) respectively associated in pairs with the reservoirs (112a, 112b, 112c) are selected, the transmitted signals (Si) are successively detected, measured and stored, and each measurement is corrected by correction values depending on at least certain of the other measurements.
