Flanged Double Window 150 PSI - Visual Flow Indicators
Sight Flow Indicators are devices used in piping systems to provide a visual indication of the flow of liquids, gases, or slurries within the system. They are crucial for monitoring and verifying the flow and condition of the media without disrupting the process.

Add-ons to improve flow visibility
Full View
For easily visible fluids, with color, turbulence, and clarity. They easily detect the presence of solids or foreign products in the handled fluid. They can be mounted in any position.
Flapper
Internally mounted with a PTFE flapper, where the position indicates the direction of the fluid. Used in clear fluids that are difficult to observe; they are normally mounted horizontally, and only in vertical positions with ascending fluids.
Drip
Allow for the formation of drops of low-volume or intermittent fluids, for example in unitary distillation operations. They are mounted only in a vertical position and descending flows.
Spinner
Internally mounted with a PTFE spinner that rotates with the passage of the fluid, widely facilitating the observation of flow for dark, translucent, and clear fluids that are difficult to observe with the naked eye. They can be mounted interchangeably in any horizontal or vertical position.
These sight flow indicators can have additions which help the user have a clearer view of the process. The Double Window Visual Flow Indicators allow for a higher number of configurations in terms of types of gaskets and types of sight glass, allowing for greater usage parameters in terms of pressure rating and high-temperature applications.

Discovering what's flowing through your process pipelines can be a time-consuming and frustrating job. You stare at your equipment and wonder, 'How do I really know for certain what's going on in there?' Fortunately, Flanged Sight Flow indicators make it easy to observe the direction and approximate rate of flow of liquid, powder, or gas through a process pipeline, as well as its color and clarity. A Flanged Sight Flow indicator has a body with one or more viewing windows, usually with gaskets, and a way to mount the indicator to the pipeline.
