Applications
Tanks and vessels
Usually use a round sight glass window installed on the vessel wall for direct visual inspection of the process inside.
Liquid level monitoring
Usually uses a gauge glass or side-mounted sight glass window to let operators check the liquid level clearly.
Flow observation
Usually uses a sight flow indicator glass or tubular sight glass so the movement of the liquid can be seen through the pipe section.
Chemical processing
Usually uses a borosilicate sight glass or tempered sight glass disc because it is better suited to chemical resistance and industrial service.
Food and beverage equipment
Usually uses a sanitary sight glass or borosilicate sight glass to support hygienic visual inspection during production.
Pharmaceutical equipment
usually uses a sanitary sight glass window or borosilicate sight glass for clean and reliable observation in process systems.
