Double Window Sight Glass Manufacturer in Mumbai India
Double Window Sight Glass
Double Window Sight Glass manufacturer in Mumbai, India, Asre Engineering manufactures premium-quality sight glasses for clear visual monitoring of liquid flow in pipelines. Also known as dual window sight flow indicators, these devices enable operators to observe the flow, clarity, and condition of process fluids through two opposite viewing windows. Built with borosilicate glass and robust housings, our double window sight glasses ensure high visibility, excellent pressure resistance, and long-lasting durability in demanding industrial environments.
Why Our Double Window Sight Glass Stand Out
- Dual Viewing Windows for better observation of fluid flow
- High Pressure & Temperature Resistance
- in Stainless Steel (SS304, SS316), Carbon Steel, and Alloy options
- Flanged, Screwed, and Welded End Connections
- Optional Internal Indicators (rotor, flap) for enhanced low-flow detection
- Low Maintenance & Easy Installation
Our double window inline sight glasses are ideal for monitoring process fluids in critical pipelines where continuous visual inspection is required.
Working Principle – How Our Double Window Sight Glass Works
The double window sight glass is installed inline with the pipeline.
It consists of two borosilicate viewing glasses mounted on opposite sides of the body. This design allows clear visibility of the liquid from both sides.
Some variants include flow indicators (rotating impellers or flappers) to make even low-flow conditions visible.
Unlike electronic sensors, this mechanical device provides real-time, fail-proof monitoring.
