Sight Glass

As a pipeline monitoring device, Armstrong sight glasses can be widely applied in the petrochemical, chemical, pharmaceutical, food or other industries. The sight glass allows you to view flow status such as presence of fluid, flow direction, and flowrate. This allows you to confirm the working condition of in-line control valves, strainers, steam traps or other equipment; as well as to identify system problems and conduct troubleshooting.
