Abstract
The device uses a sensor probe in which a plurality of electrolyte level sensor coils and/or specific gravity stratification indicators are stacked vertically in the walls of a hollow electrically insulating and chemically nonreactive elongated probe housing such that the sensor coils never come into contact with the electrolyte. Balanced transformers or series resonant coils are used to sense changes in electrolyte level and/or changes in specific gravity at various respective levels to indicate stratification of electrolyte. The fields of the sensors are changed by the amount of electrolyte in the area of the sensor coils. These changes operate to produce signals that are read as digital or analog outputs.
