Tips for using a water flow switch

The ambient temperature is not lower than 0°C. Do not knock on the housing and keep away from magnetic objects.
The output of the signal is a switch quantity, so the connection method of the control object must also be a switch control.
The power of the controlled object shall not be greater than the signal load capacity.
The water flow switch is a water medium control device and cannot be used for other medium control.
