ABSTRACT:
The charge state of a storage battery, such as a lead sulphuric acid battery, is monitored by a continuous flow hydrodynamic indicator system which includes a barrier to the movement of bubbles into the electrolyte column of the indicator system during battery charging. Clogging of the column and resulting interference with the operation of the indicator system is avoided. A digital buoyant and sunk ball indicator is used in conjunction with a binary counting circuit.
