ABSTRACT:
The invention is an improved liquid level indicator for the liquid in a reservoir. The invention consists of float mechanism in a framework which permits the float mechanism to be immersed in the liquid in the reservoir and float thereon. The float mechanism magnetically controls a companion device in a hollow enclosure, protected from contact with the liquid in the reservoir. As the level of the liquid in the reservoir changes and the float mechanism follows the changing level of the liquid, it likewise changes the position of the companion device through its magnetic control. The companion device is wired to signal the liquid level at an appropriate read-out site.
