Purpose

Mainly used for water flow switch control of electric appliances such as water heaters, humidifiers, drinking fountains. According to the different control methods of the switch, it can be used for two ways: power supply or power supply. It can be used for rapid electric water heater water supply and power control and water storage water heater water supply and power control.

Working Principle

When there is water flowing in the water flow switch and the water flow rate is ≥1.0L/min, the magnetic core in the water flow switch is pushed by the water flow to generate displacement, and the magnetic core displacement drives the magnetic source to generate a magnetic control function to make the water flow switch output a "ON" signal. The signal input device control system, through the control system to achieve the control role, when the water flow is less than the start flow, the water flow switch output "off" signal, the control system produces the opposite control effect.
