Glass-Trac Gauges, formally Daniel Level Gauge & Valve, are available in three main types: Reflex, Transparent, & Tubular. These direct reading instruments are available in many different materials to meet your specific process conditions.

Glass-Trac Reflex Gauges use prism glass to provide an excellent indication of the liquid level. All liquids appear black in contrast to the mirror-like surface above. This clean line of separation can be sighted from many yards away.

Glass-Trac Transparent Gauges use clear, see-through glass on both sides so that both the color and the interface of liquids can be viewed. Electric lighted gauge illuminators are available for use on transparent gauges and provide easy viewing of liquid levels in dimly lighted areas.

Glass-Trac Tubular Glass Gauges are available in any length desired and can be fitted with tubular style gauge valves. These gauges provide 360 degrees of visibility of the liquid level through strong, clear glass. Guard rods and plastic tubes are available as an added measure of protection.
