The invention relates to a device (2) for determining the density of an electrolyte (4). Said device (2) comprises at least two immersion tubes (9, 10) provided with an open orifice (52) and immerging at different depths in the electrolyte (4), whereby said immersion tubes can be respectively filled with gas to a depth (21, 22) which is allocated thereto and each tube has a different gas depth (d) with respect to the other. A least one differential pressure sensor (16) is used to define the difference in pressure inside the immersion tubes (9, 10). An electrode (11, 19) is respectively provided inside the immersion tubes (9, 10), whereby said electrode is connected to a voltage source (5, 35) in order to produce the required depth (21, 22) of gas so that said immersion tubes (9, 10) can be filled therewith upon contact with the electrolyte(4). |
