BFS-10-N / BFS-10-O Low-Flow Water Switches
The BFS-10-N and BFS-10-O flow switches from Barksdale monitor water and compatible liquids using a spring-loaded variable-area mechanism. The continuously adjustable switching point supports low-flow protection in cooling circuits, test systems and pump applications.
The N version has no local flow indication; the O version adds an optical display. Select the process connection, wetted material, contact arrangement and switching range to suit the application. Pressure capability depends strongly on the selected version.
