MODEL F50 DISC-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. Disc-actuated Model F50 switches are in-line type used for sensing clean liquids in 2 inch or smaller line sizes.

Operating Principle


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


- Pump staging or failure
- Pipeline flow detection
- Valve failure
- Loss of pipeline flow
- Pipe blockage/rupture
- Pump inlet flow protection

- Check valve blockage/leakage
- Alarm on eyewash or shower safety station
