A sight glass is a visual observation window used to view or monitor liquid levels and flow within a tank, pipeline, or other pressure vessel. A typical sight glass window is made up of a thick borosilicate glass, soda lime glass, quartz, or sapphire depending on the needs for each application. When selecting a sight glass substrate, glass characteristics such as thermal shock, corrosion, abrasion, pressure, and impact tolerance should be considered.
