What is the difference between the flow solenoid valve and the flow switch and the working principle?
For example, a pipeline of water, to reach a certain flow after the flow switch will give PLC a signal, and then PLC or people to the relay a signal, the relay to the solenoid valve, and then the valve is closed or smaller, in order to achieve the purpose of control flow
Flow switch is the water flow switch, as you explained, that flow switch and water flow solenoid valve can be used as a switch. Flow switch also more than a calculation of water flow function?
To answer
No, ah flow switch is just a switch, is generally responsible for the transmission of the signal. Flow switch does not mean that can calculate the flow, on behalf of a certain flow to open or pull the switch
Water relay every heard, solenoid valve, one is said by the electromagnetic control of the gas, water and other valves
Flow switch should be the level meter, a lot of points, there are radar, radio frequency, and so on
