Sight 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.
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 observation of 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.
The Double Window sight flow indicator allows 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. Flanged Double Window Sight Flow Indicator — HP model: The Gulf Coast Glass HP double window sight flow indicator has its body forged in one piece, which grants additional robustness and durability. After that, flanges are welded to the ends of the forged pipes, enabling this model to have any type of flange for every type of application.
