Longitudinal Sight Glasses
Vertical sight glasses are used for the safe visual inspection of liquid levels in closed containers, boilers, tanks, silos, and equipment. At MAXOS®, you will find a variety of models designed for welding-in or welding-on applications, suitable for various pressure ratings, temperatures, and installation scenarios. The product range includes standard models for industrial plant engineering, as well as variants with enlarged viewing ports and solutions designed for higher pressure requirements.
This allows the appropriate longitudinal sight glass to be specifically tailored to the tank, the fluid, and the operating conditions. If no suitable standard model is available, we will work with you to develop a suitable solution.
