Abstract
A local display of a fluid level is provided in connection with a fiber optic illuminating system in which a side by side, bi-color light is passed through the fluid in a level gauge having transparent viewing ports. Diverging light passing from the level gauge, refracted in response to the fluid and gauge material, is masked and one color is passed to a focusing lens and a local readout in a plane above or below the focusing lens.
