Glass-Trac - Liquid Level Gauges and Valves
Glass-Trac Reflex Gages use prism glass to provide an excellent indication of the liquid level. All liquids appear black in high contrast to the mirror-like surface above. This clean line of separation can be sighted from many yards away. Reflex Gages are made in three pressures series (maximum 4000 psig 100ºF) and are tapped for ½” or ¾” NPT connections. The standard Glass-Trac level gages are designed for minimum -20ºF service.
On Glass-Trac Reflex Close Hook-up Gages with ½” NPT connections, the center-to-center dimensions is the same as the overall length on standard gages.
On Close Hook-up Gages with ¾” NPT connections, the center-to-center dimensions is the same as the overall length on standard gages plus ⅜”.
