Sight Flow Indicators
Threaded Double Window Stainless Steel Sight Flow Indicators are devices used in various industrial applications to monitor the flow of liquids in pipelines. The key feature of these flow indicators is the presence of two windows, typically made of toughened glass or acrylic, positioned opposite each other. These windows allow for a clear view of the fluid passing through the indicator.
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.
