G1/2'' 4 Points Copper Turbine Switch Control Flowmeter Male Thread 1.5-30L/Min

Features: Good sealing effect, easy to install. Make of copper, durable, anti corrosion, high temperature resistant. Mainly used for water flow switch control of electric appliances such as water heaters, humidifiers, drinking fountains. When this product connected to a load above 50W, intermediate contactor-relay must be added, otherwise it cannot be used. Working method: When there water flowing in the water flow switch and the water flow rate ≥1.0L/min, the magnetic core in the water flow switch will receive water. The flow pushes the displacement, and the magnetic core displacement drives the magnetic source to produces the magnetic control effect, so that the water flow switch output "on" Signal. The signal input to the equipment control system, and the control system realizes the control function. When the water flow less than the starting flow, the water flow switch outputs a "off" signal. The control system produces the samereverse control.
