 Why a Jerguson Flat Glass ®

Gage is Your Best Choice

Jerguson Flat Glass Gages are simple, rugged instruments engineered and built to give you
accurate liquid level readings for the life of the vessel. The gages’ special features make
them safer, easier to service, and allow them to be re-machined to extend their life.

Our Recessed Gasket Surface:

Easier Servicing, Safer,
Re-Machineable
Jerguson gage chambers have a gasket
“pocket” that makes it much easier to
replace gaskets. This is appreciated during
bench servicing, but is especially valuable
in the field, where the recess provides a
positive locating benefit, making it possible COMPETITOR’S JERGUSON
to replace gaskets on gages in-place. Our recessed gasket surface makes our gages
easier to service, safer, and re-machineable.
A recessed gasket surface is also a safety
feature that can minimize leaks or could
even prevent a blowout. If the gage’s bolts
were to be improperly torqued, or under
certain thermal expansion conditions,
clamping pressure can be lost. If this
happens, the gage’s design will direct the
fluid to push the gasket laterally outward
and into the side wall of the pocket, rather
than causing a gasket to blow-out.
The recessed gasket surface is
re-machineable. Because the Jerguson
gage chamber is a robust 1 9/16" thick,
it can be re-milled rather than replaced if
steam cuts or pitting occur. (Competitive
gages cannot be re-machined because
they are only 1 3/8" thick.)

 Shrouded Carbon Steel Covers to
Protect the Glass Are Standard
Most Jerguson gages employ shrouded
covers which protect both the glass and Shrouded cover
personnel. The shrouds protect the glass construction
from sandblasting during re-painting — a
frequent occurrence in offshore applications.
Additionally, in the event of a leak, the
shroud will deflect the stream to protect
personnel who may be in the area.

Explosion-Proof White LED
Illuminator on the Market
The LumaStar™ EPL Series Illuminators
are super bright, with an intense white
light that cuts through dark fluids and
dirt…way better than colored LEDs!
With up to 100,000 hours of life and no
heat generation, you’ll clearly see fluid

To guarantee mechanical and chemical
material properties, all materials used in
Jerguson gages are listed in either ASME
or ASTM. This is not universally the case
for all manufacturers’ similar gages.

 Reflex vs Transparent Level Gages
Reflex Level Gages
Jerguson® Reflex Level Gages are ideal
for clean total level indication applications
for refining, petrochemical and general use.
The reflex prisms are molded and polished
to provide a crisp silver-black bi-color
indication of the fluid level. As light passes
into the reflex glass, if there is fluid
present, the light continues through the Reflex gage cross section

Transparent Level Gages

Jerguson® Transparent Level Gages are
selected for interface level indication, dirty
service or any application that requires the
use of a shield to protect the glass from
corrosion. A transparent gage is also known
as a “thru-vision” gage since the gage is
constructed with two pieces of flat polished
glass assembled on opposite sides of the
level gage chamber. Since the user can see
straight through the gage, it is also easy Transparent gage cross section

A Series 32 gage appears very similar to a Series 20, except the Series 32
Reflex Transparent gage features mid-span supports or tie-bars to allow for increased pressure
R-32 T-32 ratings. Note that the mid-span support is recessed. This is very important as
other brands do not recess their mid-span support which causes a blind spot
in the vision. A recessed gasket surface provides positive location of the seal
gasket during both assembly and field repair and also makes it possible to
repair a Jerguson gage while it is mounted to the vessel. The recessed gasket
surface is also an important safety feature in the fact that it contains the
gasket and helps prevent lateral movement which could lead to a gasket
blow-out (as with competitive gages).
Refer to page 24 for Non-Frost Extensions, page 28 for Illuminators, page 25 for
Support Brackets, PCTFE Shields, and page 7 for Mica Shields and special alloys.

The Jerguson Series 51 Liquid Level Gage is a specially designed instrument
capable of withstanding high pressures. The one-piece chamber is machined
out of solid bar stock carbon steel or stainless steel as specified. It is drilled
lengthwise and crosswise at each port leaving tie-bars in between to resist
deflection under pressure. Viton® O-Rings that seal each port are unaffected
by most liquids that cause deterioration in rubber. The O-Rings are seated in
recessed circular channels to assure proper sealing action.

Jerguson Large Chamber Gages are designed to give an accurate liquid level reading
of liquids that have a tendency to surge or boil. These gages are highly effective in:
(1) r educing the boiling effects of entrained gas being released under low pressure,
(2) e liminating apparent level fluctuations that occur in standard gages (with small
chambers) when boiling / flashing vapors try to rise to the surface, and
(3) applications where the operating temperature is below freezing and high ambient
temperatures cause the temperature of the fluid in the gage to exceed the boiling
point of the liquid. In applications where the operating temperature is below
freezing the gage must be equipped with Non-Frost Extensions.
Jerguson Large Chamber Gages are available in reflex or transparent design.
The liquid chamber is constructed of heavy tubing, carefully slotted and machined

Standard Weld Pad Gages
Available in both reflex and transparent types. Generally used for non-critical
applications. When using standard weld pad gages, the tank must be relieved of
pressure and drained to service the gage. Seal pots are a typical application.
This type of gage is not used on critical process equipment because you cannot
perform maintenance or replace a gage without shutting down the entire process.

Isolable Weld Pad Gages

Jerguson Isolable Weld Pad Gages follow the general design of standard Jerguson
weld pad gages but offer the additional advantages of integral valves. Because the
gage can be isolated from the vessel by the valves, gaskets or glass can be replaced
without lowering the level of liquid below the gage inlet or relieving pressure from
the vessel. Isolable gages are installed by matching the valve inlets with holes drilled
in the vessel and making a 100% fillet weld between the vessel wall and the valve
inlets. The gage chamber is tack welded to the vessel.

 Non-Frosting for Unobstructed Liquid Level
Readings on Low Temperature Applications

Non-Frost Extensions
Series NF
• Required for cryogenic installations, should
extend 1/2" (12.7mm) beyond insulation
• Install on Reflex or Transparent types
• For use on standard or large chamber gages

For low temperature applications where frost has a tendency to

build up on the gage or if cryogenic insulation is required, the
Jerguson Non-Frost Extension keeps frost from covering the
window and maintains clear visibility at all times.
The Jerguson Non-Frost Extension consists of a plastic extension
which makes direct contact with the gage glass and extends
beyond the cover so that the frost build-up does not obscure
Large Chamber Reflex Gage reading of the liquid level.
(RF-L10 with Non-Frost Extension)
Mounting of the plastic extension is simple and can be
accomplished without dismantling the gage. The Non-Frost
Extension can be installed or removed (for cleaning), either
before or after the gage has been put into service.

Available on Standard or Large Chamber Gages

Non-Frost Extensions have been designed for the Series 20, 32,
and L-10 gages.

Options
SUPPORT BRACKETS
Jerguson® recommends welded support brackets (see right) on gages that
exceed 165# in weight. Gages longer than (5) sections of transparent glass
typically require a support bracket for Series 20 & 32. Higher pressure gages
may require brackets at smaller lengths due to increased weight.

FIELD WELDING OF GAGES

Jerguson gages provided with socket-weld connections should be welded
without the end-section of glass assembled, unless an extended chamber is
provided. Note that if field disassembly of the gage is required then the
glass & gaskets will need to be replaced, even if they were never in service.

OPTIONAL CONNECTIONS FOR GAGES

Additional connection types are available for Jerguson Glass Level Gages.

 Coating Options
for Gages & Valves

Coating Options
FP-16 (Standard)
Basic finish coating for carbon steel, forged or cast steel product
components. Intended as a prime coat and provides protection
in general environments.

FP-11
For coastal and offshore applications, this Three-Coat system is designed
to give optimal service life in corrosive applications and environments.
• Inorganic zinc base coat
FP-16 Coating • Epoxy tie-coat
• Urethane top coat
This system includes 316SS fasteners and an acrylic protector that
covers the exposed glass on the front (and back if transparent) of
the gage. All components are coated prior to final gage assembly.

FP-11ZB
This option includes the same coating procedure as FP-11 except
zinc-plated hardware is used instead of 316SS. Ideal for coastal areas
or environments or as a more economical option to FP-11. This option
does not include the acrylic protector as standard. All components
are coated prior to final gage assembly.

FP-11CA
This option includes the same Three-Coat system as FP-11 except for
the entire gage is painted after assembly for the most economical
option when a superior level of protection is required. FP-11CA does not
FP-11 Coating include the acrylic protector as standard.
