The flow switch is based on traffic to the command system switch, depending on the flow and use different parts of their systems switch models and types vary from the categories can be distinguished: baffle flow switch (or plug-flow switch and said mechanical flow switch), thermal flow switch (also known as electronic flow switch), the differential pressure type flow switch, infrared water flow switch (also called infrared flow sensors), etc. Flow switch works is that when the water flow within the flow switch, water flow ≥1.0L / min, the flow switch within the core driven by the flow of water displaced, driven by a magnetic core displacement effect so that water source to produce magnetic switch output "Tong "Signal. Flow switch quick and easy selection of excellent automation have included, the signal input device control system, the control system for control action, when the water flow is less than the starting flow, flow switch output "off" signal. Contrary to the above control system generates control action. When the pipe in the water flow is less than 1L / min flow rate, driven by a magnetic core source return in force under the action of the return spring, the sensor outputs "0" switch signal to stop operation of the system. Flow switch with high sensitivity, durability, etc.
