A flow switch is a device which has two possible states, as switch open or switch closed, which are activated by the given flow rate. Unlike flowmeters, flow switches do not measure flow rates continuously.
The device has an activation threshold normally set far enough apart from the deactivation threshold to avoid flutter between the two. To be able to measure the flow instantaneously a digital flow switch can be used.
Flow switches can be used in control systems, where it is useful or necessary to activate a change for a specific value of flow, for example, in heating systems where temperature sensors are not located in proximity to the heating element. This prevents damage caused by an unexpected lack of circulation.
The most common flow switches are electro-mechanical devices, where a mechanical element immersed in the fluid actuates mechanical switch by means of a lever mechanism.
In these models, the response threshold can be modified by varying the length of the lever arm (pallet) or the contrasting mechanical spring. Our range includes flow ...

In these models, the response threshold can be modified by varying the length of the lever arm (pallet) or the contrasting mechanical spring. Our range includes flow switches for water, demineralised water, aggressive liquids, air and gases.
For specific uses we can also supply ATEX flow switches for use in areas with risk of explosion.
