Abstract

332,314. Smith & Sons (Motor Accessories), Ltd., S., and Watson, E. A. April 30, 1929. Indicators, electric. - Liquid-level indicating apparatus of the kind comprising the combination of a crossed-coil electromagnetic meter and a potentiometer having its slider connected to the float, has one field winding a of the meter connected across the source of electromotive force b and the other field winding c connected to the slider and to an intermediate point on the first field winding, or to a similar point on the source of electromotive force, or on a resistance in parallel therewith. The windings a, c are carried on cores g, j, the armature h responding to the resultant field.
