Glass-Trac Reflex Gauges 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 Gauges are made in three pressures series (maximum 4000 psig @ 100ºF) and are tapped for ½” or ¾” NPT connections. The standard Glass-Trac level gauges are designed for minimum -20ºF service.
On Glass-Trac Reflex Close Hook-up Gauges with ½” NPT connections, the center-to-center dimensions is the same as the overall length on standard gauges.
On Close Hook-up Gauges with ¾” NPT connections, the center-to-center dimensions is the same as the overall length on standard gauges plus ⅜”.
