The Magnetic Level Indicators can mount horizontally with side connections to a tank, or vertically to be mounted on top of or below a tank. Each float includes a magnet assembly. As the tank level increases and decreases, so does the precision float. The magnetic flux of the float affects the bar-graph indicator assembly mounted outside of and isolated from the application conditions. This allows visual indication of process level without the threat of environmental or personnel injury due to glass gauge leakage or failure.
