Abstract

A plurality of identical electrodes (6) distributed vertically in the liquids is used. Measurement of the voltages of electrodes makes it possible to determine the number of electrodes dipping into the more conducting or less conducting solution, which makes it possible to determine the position of the level of separation. Application to locating the level of separation between two liquids with electrical conductivities which are only slightly different from each other. <IMAGE>
