LIQUID LEVEL GAUGES REFLEX AND TRANSPARENT OFFSET TYPES |

"
CRISTAL" offers tubular type liquid level gauge
glasses for accurate
observation of levels in process tanks, stills or any
liquid container used
in process work. Thery are rugged, simply constructed
and efficient. Flat
glass gauges are made in both Reflex and Transparent
types.
Reflex Gauges:
give a clean line of separation, with liquid
showing black in contrast to
the mirror-like surface above.
Transparent Gauges:
Levels, colour and interface of the liquid can be noted
through heavy
duty transparent glasses. Both types are made in
pressure group
upto 250 kg/cm2 @ 400 C
Construction :-
Liquid Chamber :
The liquid chambers (Single or Multiple section)
are made in one piece
from a solid bar of C.S, S.S. etc. having high physical
properties at
elevated temperatures. They are accurately machined and
ground to
give perfect gasket seating for glass.
Cover:
Made from a solid bar of steel and is jig drilled
for interchange ability.
Glass :
Tempered glass,chemically stable and absolutely
transparent, is suitable
for use at high pressure and temperatures and resist to
chemical attack
of all fluid except hydrofluoric acid and caustic
solutions. For steam and
alkaline fluids mica shields are recommened as
protection to give longer
life to transparent glasses, Reflex glasses have
perfectly molded
reflecting prisms.
Gaskets :
Die-cut from highest quality material best suited
for use with liquid being
gauged and guaranteed perfect seal and absence of
mechanical stress
on the glass.
Bolts & Nuts:
are made off special alloy steels.
Valves :
are designed to provide long trouble free service
at economical cost
They are made from solid bar of different material to
meet specific
requirement. Accurate machine work throught is adopted.
Their design
incorporated such quality features as stainless steel
stem, seats and ball
checks.
Union gauge Connections :
Are provided along with valves, which allow a top
and bottom connected
gauge to be turned to any desired angle for convenient
visibility. It also
makes the liquid from the vessel-a feature which saves
times when
gauge must be cleaned or maintained.
Safety Shut-off :
Valve are provided with a
stainless steel ball check which
instantaneously shut off flow of medium in case of
gauge glass
breakage or failure of gasket.
Both Reflex and Transparent gauges are available with
endside
and back connection and they are made 'in-line' and '
offset'
wih the type of connection to fit your need.
Our standard connection is 1/2" or 3/4" NPT (male)
screwed.
Special Function Gauges :-
1. Non-frosting Gauges :-
They are made in both reflex and
transparent types of unobstructed liquid level readings of low
temperature fluids. A special frost-preventing unit projects beyond
the cover bolts so frost cannot build up across the vision slot in the
cover.
2. Large Chamber Gauges :
They are used
under unusual conditions
such as where the liquids having solids in suspension.
The gauges will
become an integral part of the vessel.
3. Welding Pad Gauges :
This type is recommended for
reading the
levels of liquids having solids in suspension. The
gauges will become an
integral part of the vessel.
Heated Gauges :
This applicable when
working with liquids which must
be kept at higher than ambient temperatures for process
reasons or to
hasten the speed of response to level changes. They are
also ised to
prevent breakage of gauges through freezing in winter.
These gauges
may be heated with steam or liquid, or may be
electrically heated.
