Vessel fluids may be pressurized and can
unexpectedly exit vessel connections due to
apparatus or material failure. Safety glasses
should be worn when installing a gage scale.
Failure to follow any instruction could possibly
result in an inability to measure the contained
fluid accurately or a malfunction of the liquid level
gage with resulting sudden release of pressure,
severe physical injury or property damage.

2 IntrOduCtIOn

Penberthy flat glass gage scales are used to
measure the level of the contained fluid in the
pressure vessel or holding tank. Penberthy
standard flat glass gage scales are made of
a strong weather resistant metal that has a
natural finish with black graduation marks that
contrast with the finish of the scale for ease of
reading. Penberthy standard flat glass gage
scales are furnished in customer specified
increments and lengths and are assembled
complete.

2.1 standard scale description

Penberthy standard flat glass gage scales
comprise three basic components. Use the
exploded parts view in section 10 as additional
reference material.
scale: a metal strip with markings as customer
specified.
backing plate: an aluminum strip onto which
the scale is attached to give the scale some
rigidity.
Mounting bracket: used to hold the gage scale
in position on the flat glass gage. The mounting
bracket is attached to the gage bolting by use of
the existing nut and bolt and the gage scale is
held in position in the bracket with a set screw
provided with the bracket.

2.2 special scale description

Penberthy special flat glass gage scales are
provided completely assembled. all parts of
the gage scale are mounted onto the backing
plate during factory assembly. The mounting
brackets are the only components which are
not assembled to the gage scale.
