Clay & Bailey - 1313 Series - AST Sight Gauges
Designed for measuring the liquid level in
AST's. Entirely mechanical in operation.
Sight gauge is readable up to 20 feet in height
and visible from a distance of 12 feet. Easily
installed in a 3" or 2" riser opening on top of
the AST. Highest quality materials are used
in the construction of the gauge, and it is
impervious to most fuels. Accurate to 1/16th
of an inch, with light aperture in top for easy
viewing night or day. Tape, float and other
parts are safely installed through the riser
pipe into the AST, minimizing the chance
of vandalism. Sight gauge may be combined
with an audible alarm.
