Professional Water Flow Sensor Switchs DN20 External Threaded Flow Sensor Edition 0313

Usage Tips:Features:Good sealing effect, easy to install.Make of brass, durable, anti corrosion, high temperature resistant.Mainly used compatible with water flow switchs control of electric appliances such as water heaters, humidifiers, drinking fountains.When this product connect to a load 50W, intermediate must be added, otherwise it cannot be used.Working method: When there water flow in the water flow switchs and the water flow rate 1.5L/min, the magnetic in the water flow switchs will receive water. The flow pushes the displacement, and the magnetic displacement drive the magnetic source to produces the magnetic control effect, so that the water flow switchs 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 switchs outputs a "off" signal. The control system produces the samereverse control.
