Sight Glass

The most common application is flow indication. The Sight Glass is fitted in the pipeline to indicate if the fluid is flowing correctly in the line. These can therefore be used to indicate blocked or choked valves or Traps, strainers, pipelines or piping components which otherwise would lead to a decreased level of performance, plant efficiency and safety.

The sight glasses would indicate if the traps are leaking or passing live steam/vapors.A sight Flow Indicator is a device which is inserted in a run of pipe to observe the flow of fluid in the pipe. To enhance the visibility of the flow, protrusion is often incorporated body of its indicator, in the flow stream, so that fluid impinging on the same, cause turbulence, which indicates flow.

This enables one to on observing the working of traps and other equipments by giving a clear view of the inside using toughened Borosilicate original Klinger sight glasses.

Sight glassis a product that allows to visualise the flow of steam,
Water or oil inside pipeline. The visualisation of flow helps to identify the problems occurring in system.
Upstream or downstream of the sight glass helps to overcome the problems of poor visibility and improper distinction between vapour and condensate flow.
The large window of oil-lapped toughened borosilicate glass, which resist the etching and sludge build-up, as compared to the normal glass used in other sight glasses.
DM water line, Oil line, Heat exchangers.
Condensate lines: Sight glass can be fitted on a condensate line to monitor steam flowing with the condensate.
Do not allow dust / dirt / grime to settle on external surface of sight glass, especially on the glasses, regularly clean the glass with a mild detergent, and while reassembling always use new gaskets.
