Safeguard Level Gauge

U.S. Patent Number 4693117


Safeguard gauge replaces tubular glass that is mounted between tubular gauge glass valves.  The packing nut on the tubular valve tightens around the metal nozzles of the Safeguard gauge, not glass.  Nozzles match the O.D. of 5/8″ glass or 3/4″ glass.


Sight tube is totally enclosed on three sides by a metal frame and on the front with a clear, Polycarbonate shield.

One Piece Assembly

One continuous gauge provides total visibility of the liquid level of a tank (Maximum length is 25 feet).  No stacking of gauges is needed because of this design.


One Liquid Level Gauge per tank with two valves gives the full view of the liquid level in the tank. (KENCO KTV Valves must be ordered separately)

Easy to Install 

Remove the broken gauge glass from the stuffing box of the valve. Insert the 5/8″ or 3/4″ metal nozzles into the existing valves.  The stuffing box seals around the metal nozzle, not the glass.

Volume and Height Shields

The Polycarbonate shield can be supplied with various scales indicating height in inches, calibration rate, or tank volume.  Refer to the Specifications tab to see the assortment of standard shield options.
