Model F10 Vane-actuated Mechanical Flow Switch
Flow switches are highly reliable devices sensing the start or stop of flow in horizontal pipelines containing oil and petroleum derivatives, chemicals, water, or air. Vane actuated model F10 switches are used on gas or liquid flow applications in 2″ or larger pipe sizes. Disc actuated model F50 switches are in-line type sensing clean liquids in 2″ or smaller pipe sizes.
Operating Principle
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.
Applications
- Pump staging or failure
