What is a flow switch?
Flow switches are typically used to control the flow of liquid or gas through a designated channel. A flow switch can activate if the volume of the flow is too great or too little.
How does a flow switch work?
Flow switches are activated by a connected paddle, that is displaced as water or gas passes. If the volume of passing substance is too high or too low, the switch will shut the circuit off to prevent damage elsewhere in the system.
Where are flow switches used?
- Triggering an alarm if a supply shuts off
- Shutting down an electric motor during insufficient flow
- Air conditioning / ventilation units
- Central heating systems
- Swimming pool chlorination systems
