Sight Glasses are used in Oil & Gas Industries for monitoring fluids in pipes and vessels. These are highly accurate, reliable, and economical instruments that provide continuous visual displays of the liquid level in process or storage tanks. The sight glass provides a clean, clear view of the liquid level inside the tank without disturbing the process flow rate or pressure conditions inside the vessel or pipeline.
