Sight Glass

At Flowlink Valves & Controls, Tank Mounted Sight Glasses are designed for visual inspection of static process media in reactors, storage tanks, and other vessels, providing a safe and distortion-free view of processes without interrupting operations. Beyond basic observation, these sight glasses allow monitoring of liquid flow, color changes, fluid levels, and process conditions. Constructed from Borosilicate Glass 3.3, they ensure high durability against extreme pressures, temperatures, thermal shocks, gradients, and corrosive chemicals. These units are typically installed above the maximum liquid level and are fully customizable to meet diverse industry needs. Available sizes range from 25NB to 300NB, catering to various industrial applications with robust performance and reliability.
