The sight glass with nozzle Weld of rectangular sight glass fittings is welded onto or into the vessel wall. Then the sight glass plate together with two seals is firmly bolted down by the cover frame and a set of fastening bolts. Operating Conditions: It is strongly recommended to check the strength of reinforcement around the cutout in combination with the vessel wall . Pressure: 16 bar, vacuum
For viewing the internals of vessels, silos, reactors etc.; mainly used as fluid level indicator.
General:
The base frame of rectangular sightglass fittings is welded onto or into the vessel wall. Then the sightglass plate together with two seals is firmly bolted down by the cover frame and a set of fastening bolts.
Operating Conditions:
It is strongly recommended to check the strength of reinforcement around the cutout in combination with the vessel wall . Pressure: 16 bar, vacuum
Temperature:
100° C with soda lime glass, DIN 8903
243° C with borosilicate glass, DIN 7081
Those temperatures refer to unprotected glass plates, i.e. without mica protective sheet.

Reflex Level Gauges
1.Reflex Level Gauges are ideal for clean service and non-viscous applications
2.Provides an easy to read black-silver indication (black = liquid, silver = vapour).
3.Solid construction and tempered borosilicate glass
4.Also known as “prismatic” level gauges
Transparent Level Gauges
1.Transparent Level Gauges are ideal for dirty, corrosive services and process steam
2.Solid construction, using tempered borosilicate glass windows with the option of mica shields
3.Also known as a “through-vision” gauge or “clear” level gauges
4.An illuminator is always recommended to be fitted for easy reading of the gauge
Options and accessories:
1.Various valve options including: •Integral, union and OS&Y bolted bonnets
•various connection styles
•offset pattern for easy cleaning
•standard top/ bottom connections or side hook-up for increased visible length
•safety shut-off ball checks
•regrindable / renewable seats
•bleed fittings
2.Speciality materials of construction
3.Illuminators for improved visibility
4.Non-frost extensions for low temperature service
5.Aluminosilicate glass for high temperature service
6.Expansion coils for high temperature service
7.Insulation jackets for the gauge and valves
8.Welding-pad gauges
9.Off-shore coatings
