Inline stainless steel sight glass with glass tube
The glass tube sight glass consists of connecting flange, glass tube, extension bolt and sealing gasket.The glass tube fixed flange clamps the glass tube, and is fixed with the extension bolt. The pipe is connected with the flange through the connecting conduit, thus forming a whole glass tube tubular.
Glass tube sight glass can observe the flow of liquid, gas, steam and other media at any time, is an indispensable accessory to ensure normal production.Has reasonable structure, convenient operation, good sealing performance, high working efficiency, alkali resistance, acid resistance, non-toxic, model design and beautiful strong wait for a characteristic, is widely used in chemical, pharmaceutical, metallurgy, dye, food, sugar, wine making, ceramics and environmental protection industries, drainage or worse before the solid flow, cooling water and other liquid tube to observe the liquid flow on the road.

Tubular Sight Glass
Tubular Sight Glass is used for monitoring flow in pipelines for a wide range of applications.These SightFlow Indicators are bi-directional type and easy to install in any orientation.Full view type Sight Glass FlowIndicators are widely used for corrosive chemicals, acids and colored liquids.
Tubular Sight Glass can be installed vertically or horizontally in the middle of any kind of non transparentpipeline and are very convenient & easy to observe the flow from any direction.
Tubular Full View Sight Glass (Sight Flow Indicators) are generally used in processes, where spot required to detect presence of media, or to visual inspect color, clarity, turbidity, or other critical characteristics.Full View Sight Glass provides a quick, reliable and economical way to verify the flow of liquids throughindustrial process pipe lines. Full View Sight Glass is available with different length of glass from 4"(100mm) to 8"(200mm) long.
