Flow Sight Glasses DOUGLASS flow sights with bubble traps allow the user to observe the process in question to monitor abnormal colors or densities in the fluid.

Due to their design, these sights are used to remove bubbles that naturally form in processes such as distillation, evaporation, and various chemical reactions. The most common measurements in which they are manufactured are with 3 sanitary CLAMP connections. The central connection supplies the fluid to the system, and the lateral one drains the same fluid. This type of sight is commonly used in distilleries and chemical processes where fluid mixing causes unwanted gases in the system.
