Longitudinal sight glass for level indication 16 bar

Oval Longitudinal Sight Glass Type 338 PN16

The ACI tank sight glass type 338 for welding-in or welding-on is suitable for visual inspection in the tank for pressures up to 16 bar. The sight glass enables reliable monitoring of the filling level with a viewing width of 50 mm. The tank sight glass type 338 is a robust oval tank sight glass that combines the advantages of a round tank sight glass for visual inspection of the inside of the tank with the possibility of level indication.

The glass material we use is industry proven borosilicate glass similar to DIN7081. Borosilicate glass is already highly resistant to most acids in its original state, but should strong alkaline media be present, it is possible to use one of our custom-made mica or FEP discs to protect the glass surface.
