Question:

What are the use of flow switches?

What are the use of flow switches? Flow switch switch alarm point is generally what will be used? What are the traffic monitors with upper and lower limit switches? How are they installed?

Answer:

First, the definition of flow switch: The flow switch is a sensing controller that uses various principles to measure the flow of media in the pipeline and transmit it to the back-end device in turn. Second, the use of flow switch: The flow switch is based on the flow to instruct the system switch. Set the upper or lower limit of the flow switch. When the flow reaches this limit, the flow switch will signal or alarm. The system will run or stop. General requirements of the flow of the system will use the flow switch. According to the different systems, as well as flow switch models and other factors, the use of different places, according to the specific circumstances.

Third, the flow switch works: Water flow switch working principle When the water flow within the water flow switch, water flow ≥ 1.0L / min, the water flow within the core of the core driven by displacement, the magnetic displacement of the magnetic field to produce magnetic control of the water flow switch output "signal. The flow control is systematically controlled by the control system. When the flow rate is less than the starting flow, the water flow switch outputs the signal of "off". The control system produces the opposite control effect as described above. In other words: when the water flow in the pipeline when the water flow is greater than 1L / min flow, the core under the action of water displacement and drive the magnetic source to produce magnetic control so that the sensor output "1" switch signal, the signal input to Equipment control system, the power expansion after the realization of the purpose of water flow control. When the flow of water in the pipeline is less than 1L / min flow, the core in the return under the action of the spring to push the magnetic source back to the sensor output "0" switch signal to stop the system work. Flow switch with high sensitivity, durability and other advantages. Fourth, the advantages of flow switch: 1, water flow switch low flow rate (volume) action; 2, the flow switch structure is simple, action contact surface is small; 3, water flow switch low content of debris flow can also be applied; 4, water switch special debris can be cleared when the line.
