Electrolyte solution level gauge for electrolytic cells and/or batteries

A level gauge (1, 20) of the electrolyte solution (L) present inside electrolytic cells (C) and/or batteries is disclosed, comprising a support element (4) provided with two or more conductive members (2, 3; 12, 13, 14) separate from each other and adapted to be inserted inside said electrolytic cells (C) and/or battery. The conductive members (2, 3; 12, 13, 14) are electrically cooperating with a signalling device (6) adapted to issue a perceptible signal when the electrolyte solution (L) is wetting at least two of said conductive members (2, 3; 12, 13, 14).
