Abstract
A transducer and battery performance indicator which senses various levels of specific gravity and other conditions of a liquid or electrolyte of varying degrees of translucency and converts the measurements into electrical analog signals which are fed to an indicator read-out. The device may include temperature and level sensors, as well as an agitator for circulating electrolyte, and a number of them are used remotely to monitor a bank of batteries.
