Abstract
Device for determining quantities of products contained in adjacent ones of plural reservoirs, by using a capacitive arrangement. According to the invention, two electrodes of the capacitive arrangement are disposed between two reservoirs and are in each case either sending electrodes to which a signal is applied, or receiving electrodes which transmit a signal. By virtue of this arrangement, it is possible to reduce parasitic coupling between different capacitors of the capacitive arrangement.
