Model F10 vane-actuated mechanical flow switch
Magnetrol® flow switches are highly reliable flow control solutions utilized to sense the presence or absence of flow in horizontal pipelines. Model F10 switches are vane actuated for use on gas or liquid flow applications in 2 inch or larger line sizes.
Mechanical flow switches
F10: Force of liquid or gas flow against a vertical flow vane mounted in a line causes the vane to pivot to a horizontal position, moving an attraction sleeve into the field of a switch magnet. This pulls the magnet toward the sleeve and actuates the switch.
F50: The force of liquid flow through a valve body and against a flow disc causes it to lift out of the flow path. The attraction sleeve at the top of the disc assembly moves into the field of a switch magnet, attracting the magnet and actuating the switch.

Applications
Operating principle
The actuating vane is magnetically linked to a pivoted electric (or pneumatic) switch, which is isolated from the process by a non-magnetic barrier tube. As the actuating vane moves with an increase in flow, it drives a magnetic sleeve into the field of a permanent magnet located outside the barrier tube which trips the switch. As flow decreases, the actuating vane returns to a vertical position, allowing the magnet and switch assembly to return to the “No Flow” position.
