A flanged sight glass, also known as a flanged sight window, is a device used in industrial applications to observe processes inside pressure vessels, pipelines, and equipment. It consists of a glass installed within a metal flange. The flanged connection allows for easy installation or replacement of the sight glass in the system without the need to dismantle the entire equipment. Flanged sight glasses enable operators to visually monitor processes such as liquid levels, colors, and the presence of bubbles.
