Flow Switches for Gas Boilers

What is a Flow Switch?

A flow switch is a mechanical switch that is switched on or off in response to the flow or non-flow of air or water. It’s typically operates through the use of a paddle which gets displaced due to the force of fluid moving past it. When the switch senses the flow of air or water if will send a signal to other devices in the system, such as the pump. The flow switch can indicate to the pump to switch on or off. A flow switch might be used to protect a central heating element from being energized before the air flow from the blower is established. These might also be used to alarm if flow rates are too high or too low.
