Flange Sight Glass – Effective in Most Harsh Operating Environments

Flange Sight Glass, also known as flow indicator, is a device generally installed on industrial pipes, tanks and vessels. Most competing units consist of a piece of glass sandwiched between two metal flanges and two sealing gaskets. It is one of main accessories used on industrial pipeline installations to allow users to observe the flow reaction of liquid, gas, steam and other media in the pipeline to ensure its safe production and prevent accidents from happening.
