SPIRAX Marshall Sight Glasses

Spirax sight glasses
the forbes marshall sight glass is a novel product that allows you to visualize the flow of steam, water or oil inside pipelines. The visualization of flow helps diagnose problems occurring in equipment upstream or downstream of the sight glass.
It overcomes the problems of poor visibility and improper distinction between vapor and condensate flow by using a deflector plate to separate the vapor and condensate. This new design is ideal for applications in which one wants a clear indication of flow, such as downstream of paper drying cylinders, in dm water lines or monitoring steam traps and heat exchangers
