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 beyon 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 thelevels 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.
