A device according to the invention is characterised in that it includes two taps P, P1 made on the tank 14 at levels N, N1 situated respectively above the maximum level and below the minimum level of the interface N2 of the liquids, and, at a distance from the tank 14 a differential pressure transducer 33 with two inputs connected respectively to the two taps by pipes 31, 37 filled with a so-called transmission liquid, while a computer means is coupled to the output of the differential pressure transducer, so as to convert the differential pressure on the transducer into an indication of the level of the interface. <IMAGE>
