Flow Switch

Flow Definition

Flow means the physical movement (velocity) of liquid, gas or steam in a pipe that causes a switch to actuate. No-flow means a decrease in velocity or, sometimes, complete stoppage, allowing the switch to revert to the original position.

What Is a Flow Switch?

A flow switch is a mechanical device that is switched on or off in response to the flow (or lack of flow) of air, steam or liquid. Flow switches are widely used in domestic air conditioning, heating and hot-water systems. It sends a "trip signal" to a different device in the system, such as a pump. The flow switch can indicate to the pump to shut off or to turn on. Some of the general uses are for pump protection, for cooling-circuit protection and alarms for too high or too low flow rates.
