Project Description

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

Addcon Full View Type Sight Flow Indicators are Bi-Directional and may be placed in any orientation and easy to check flow from any side of Sight Flow Indicator. It can be installed vertically or horizontally in the middle of any kind of non-transparent pipeline and are very convenient to observe the flow.

Addcon Engineers take pride for having Addcon make highest range of sight glass i.e. tubular sight glass Ellen Key Fitted, Tubular Sight Glass with PTFE bush, Double Window Type Sight Glass etc.

Addcon Tubular Sight glasses with PTFE seat and with PTFE BUSH, both are manufactured in several type of material of construction like in investment casting, mild steel, cast steel and bar stock. Generally these sight glasses are manufactured in 4 inch and 6 inch length of glass tube. Flange end connections compliance with ASME, BS, DIN standards. This unrestricted full view sight glass can be supplied with Special length and special face to face, on request. Full visualization and easy maintenance is another advantages of tubular sight glass. At Addcon Engineers, all sight glasses are being fully inspected and tested according to standard set up by our quality control department
