Optimum electrolyte level sensing method and the automatic topping up apparatus for storage wet cell

摘要

The optimum electrolyte level sensing method and the automatic topping up apparatus for storage wet cell are disclosed. The difference in the conductivities between the distilled water and the electrolyte is utilized. An injection outlet portion (15), an adjust ring (14), and two wires are used to detect the optimum electrolyte level to supply distilled water to storage cells. The feedback control to maintain the constant optimum electrolyte level of storage cells is carried out by a single microprocessor.
