Industrial Sight Glass & Tank View Glass

“High-Visibility Borosilicate Sight Flow Indicators for Pipelines, Reactors & Storage Tanks. Industrial Sight Glass for chemical plant & Tank View Glass – High-Performance Borosilicate Monitoring Systems (DN25–DN150)“

A Sight Glass (Sight Flow Indicator / Tank View Glass) is an industrial inspection device installed on pipelines, reactors, storage vessels, and process tanks to provide real-time visual monitoring of flow, level, clarity, color, and process condition — without interrupting operations.

At Aarohi Scientific, we manufacture heavy-duty industrial sight glasses engineered for:

Chemical processing
Pharmaceutical plants
API manufacturing
Petrochemical systems
Food & beverage industries
Effluent treatment plants (ETP)
Fertilizer and specialty chemical plants

Our systems are designed for high temperature, high pressure, and corrosive media applications.

Types of Sight Glasses (Borosilicate sight flow indicator) We Manufacture

1. Full View Tubular Sight Glass (Sight View Glass)

360° visibility
Borosilicate 3.3 tube
Ideal for horizontal & vertical pipelines
Best for flow verification and clarity inspection

2. Double Window Sight Glass (DIN 7080)

Two opposing toughened glass plates
Suitable for higher pressure applications
Easy glass replacement without dismantling pipeline
Better safety for hazardous media

3. Weld Pad Sight Glass (Tank Mounted View Glass)

Direct welded installation on tanks or reactors
Leak-proof permanent mounting
Used in reactors, storage tanks & process vessels
Available in flat, capsule, and round types

4. Jacketed Sight Glass

Double-wall construction
Heating/cooling media circulation
Prevents condensation & crystallization
Ideal for temperature-sensitive chemicals

5. Wiper Type Sight Glass

Manual/Mechanical wiping system
Maintains visibility in slurry or sticky media
Suitable for fertilizer & viscous applications

FAQs

What is a Sight Glass?
A sight glass is a transparent inspection window installed on industrial pipelines, tanks, or reactors that allows operators to monitor fluid flow, level, clarity, and process condition without opening the system.
What material is used in industrial sight glass?
Industrial sight glasses are typically made from borosilicate glass or toughened glass mounted in stainless steel (SS304 / SS316) or carbon steel bodies with PTFE gaskets.
What temperature can a borosilicate sight glass handle?
Standard borosilicate sight glasses can operate up to 200–250°C depending on design and pressure rating.
