With the highly visible PTFE spinner the style S sight flow indicator is used to check the flow of a liquid in a pipeline.

It can be used in vertical or horizontal lines and is ideal for flow monitoring in full pipes.

Sight glasses and sight flow indicators are primarily used to view the flow of gas or liquids within the water, chemical, oil and gas, power, pharmaceutical and food processing industries.

Sight flow indicators are used to view the flow of gas and liquids giving a clear visual indication of flow within a pipeline or vessel and leak detection for plant and equipment protection.

Option

Body – Primary Flowpoints can supply sight glasses in special materials such as super duplex or low carbon steels. Sight glasses conforming to NACE MR0175 can be produced. For particularly corrosive applications the body and flap can be lined with HALAR, ECTFE or PFA.

Glass – High pressure toughened soda lime to BS3463 rated to 60 bar, toughened borosilicate to BS3463 or DIN7080 rated up to 16 bar. The high pressure range uses powder coated mild steel covers as standard. Stainless steel covers are available as an option.
