Introduction To Union Sight Glass based on DIN 11851

The Alfa Laval Union Sight Glass, based on DIN 11851, is designed for direct, distortion-free visual inspection of process conditions, products, liquid levels, and cleaning inside storage tanks, mixers, reactors, and other vessels. This sight glass is suitable for high-pressure and high-temperature processes. Affordable and easy to operate, the leakproof sight glass enables operators to view the color, clarity, turbidity, or other critical characteristics of the product or cleaning status inside the vessel. Operators can use the sight glass to inspect and detect issues early on, allowing for quick responses to prevent costly downtime, protect plant equipment, and enhance operational efficiency.
