A full view sight glass is a type of sight glass that provides a clear, unobstructed view of the fluid inside a pipeline. Unlike other types of sight glasses that may have limited visibility due to small windows or obstructions, a full view sight glass typically has a large, circular window that allows for a complete view of the fluid.

Full view sight glasses are commonly used in industries where it is important to visually inspect the fluid inside a pipeline, such as in the food and beverage industry, where the quality and consistency of the product is critical. They are also used in the chemical processing, pharmaceuticals, and water treatment industries, where it is important to monitor the color, clarity, and flow of the fluid.

Full view sight glasses are typically made of materials such as borosilicate glass, which is known for its high resistance to thermal shock and chemical corrosion. Some full view sight glasses may also include additional features such as built-in lighting or wipers to improve visibility in low light or dirty environments.
