The flow switch is an electronic device for the automatic switching on and off of single-phase pumps with a power of up to 1.5 kW (2 HP). It is equipped with an automatic restart function, which ensures repeated attempts to start the pump in case of water shortage (4 attempts in 60 minutes). The device regulates the flow and has a built-in water reserve system.

For more frequent small water withdrawals or systems with small leaks, it is recommended to install a small pressure tank (8 l to 24 l) to reduce the number of pump starts.
