INSTRUCTION MANUAL AND PARTS LIST
DESCRIPTION
The F10 is a vane type flow switch designed to be installed
in 2" through 30" horizontal pipeline by means of a threaded
or flanged connection.
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 ① into the field of a permanent magnet ② located
outside the barrier tube ③ 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.
