Cylindrical Sight Flow Indicators

The Full-View Sight Flow Indicators are recommended for low-pressure applications where maximum visibility is needed. In addition to standard length models, Jacoby Tarbox offers customized lengths up to 48" (in 1/8" increments).  Available in NPT threaded-end and flanged designs, these Sight Flow Indicators are designed to enhance the visibility of process media as it passes through the glass cylinder.  Full 360o viewing area expands the number of positions and locations in which the unit can be mounted for full visibility.

Full-View Sight Flow Indicators are unique because the "characteristics" of the liquid can be viewed.   A typical sight flow allows observation of liquids through a glass pane while the Full-View sight flow allows observation of liquids in transit through a more dynamic, 3-dimensional pipeline.  Designing the Full-View to match the pipe diameter streamlines the liquid flow through the sight flow and helps to keep solids from settling.

Units are best suited for vertical applications.  Horizontal mounting is acceptable if there is no mechanical strain imposed on the glass cylinder.
