Abstract:
Device for determining the density of an electrolyte (4) with at least two immersion tubes (9, 10, 44) submerged with an open tube opening (52) at different depths into the electrolyte (4), which can be filled with gas up to an assigned depth (21, 22, 48) and have a fixed gas depth difference (d), and with at least one pressure sensor (16) for determining the pressure difference in the immersion tubes (9, 10, 44), wherein a voltage source (5, 35) is connected to electrodes (11, 19, 45) is arranged in the immersion tubes (9, 10, 44), with which gas can be generated upon contact with the electrolyte (4) for filling the immersion tubes (9, 10, 44) up to the corresponding gas depth (21, 22, 48).
