Product introduction
FSF-YK low volume liquid flow switch is mainly used to measure and control the flow of liquid through the pipe, such as water, glycol, etc.

Its typical application is in the places where chain reaction or cutout protection is needed.

The low volume liquid flow switch is a paddle flow switch, suitable for water flow cutout protection of water source / water loop heat pump air conditioning units and heat pump water heaters.

Using a large load single-pole single-throw (SPST) switch featured by quick action ensures the instantaneous performance of the flow switch.

Its shell is made of special plastic with high density and low thermal deformation coefficient. The reed switch is the main component, which can be applied to all kinds of environments.
