Project Description

A sight glass is transparent tube through which the operator of a pipeline, tnak or boiler can observe the level of liquid contain within or can observe flow of media.

In process industries process fluids are transferred from one place to other through long pipe lines. Inspection, review or observation of these transferred fluids is must. Some time pipe line may clogged due to one or another reason, in such cases also observation is necessary for maintenance. This is done by sight glass assembly, sight flow indicators.

Addcon Engineers manufacturing Double Window Type Sight Glass in Cast Construction & Fabricated design to meet an industrial requirement of various applications to inspect the process fluid. As the body have two side inspection view arrangements by the help of glass window so it is called as Double Window Type Sight Glass Flow Indicator.

Addcon Double Window Type Sight Glass available with various thickness and diameter of glass to suit various applications respects to fluid pressure and temperature. Double Window Type Sight Glass (Sight Flow Indicator) is very easy to replace glass without dismantling the whole Sight Glass assembly from process line.

Depend on process media, its working temperature and working pressure thickness of glass select and selection of the glass is base on DIN 7080 International Standard.
