Sight Glass Function

what is sight glass

Our sight glass rods are versatile tools that enable you to monitor pressure changes and perform a wide range of functions typically associated with sight glass windows.

Their primary purpose is to provide engineers and plant managers with a non-intrusive means of examining their systems, ensuring smooth operation without disrupting the internal environment.

Explore Our Sight Glass Application

Sight Glass has a wide range of applications in industrial and mechanical fields. It monitors and observes the behavior and properties of fluids or gases, providing real-time visual feedback to the operator.

In fluid piping systems, Sight Glass is used to determine liquid levels, detect flow rates, observe fluidity, and detect leaks. It helps operators ensure proper fluid flow through the pipeline and prevent clogging and overloading, improving system efficiency and safety.

In addition, Sight Glass is widely used in vessels and reactors to observe mixture uniformity, sediment build-up, and the presence of gases.
