Abstract
A liquid level measuring system includes a housing mounted to a container and a flexible coupling connected between the housing and a tubular frame suspended in a container holding a liquid. The flexible coupling maintains the tubular frame in a vertical orientation in the container. The tubular frame has a pair of 270° rifling grooves therein. A float is mounted in the tubular frame. The float has a pair of projections that extend from opposite sides portion thereof into the rifling grooves so that the float is force to rotate as it moves vertically in the tubular frame to seek the liquid level. A magnetic coupler assembly transfers movement of the float to an indicator. The magnetic coupler assembly includes a pair of facing dielectric discs. Each dielectric disc has three magnets mounted thereon with opposite poles facing one another.
