Volume switch strict, never let up the flow switch is based on traffic to the command system of the switch. The flow switch is set to the upper or lower limit, when the flow reaches the limit, the flow switch signal or alarm, the system will run or stop. General requirements for the system will use traffic flow switch. Depending on the system, and the flow switch type and other factors, where the use is different, according to the specific circumstances. Flow switch works when there is water flow within the flow switch, when 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 "ON" 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. In other words: When the flow switch when the line of water flow is greater than 1L / min flow rate, the core displacement under the action of water and promote the role of magnetic source generates magnetic sensor outputs "1" switching signal, which is input to the equipment control system, after power amplification to achieve the purpose of expanding the water flow control. 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 and other advantages. Advantages of the flow switch (a) flow switch low-flow (volume) action; simple (ii) flow switch structure, operation small contact surface; (iii) low levels of debris flow flow switch can also be applied; (iv) special hybrid flow switch When was blocking online clear.
