How to use the flow meter to control the valve opening degree
The flowmeter can only test the flow in the pipeline, and then return the measured flow to the system. The system controls the valve opening degree in the valve according to the flow ratio. The process is like that.
Electric switch valve is open the valve is turned off the power off, switch solenoid valve is through the voltage or current to adjust the opening of the valve, he needs a change in the amount, is completely personal understanding.
The problem seems a bit far-fetched.
The flowmeter can only test the flow in the pipeline, and then return the measured flow to the system. The system controls the valve opening degree in the valve according to the flow ratio. The process is like that.
If you want to use a separate flow meter to control the valve opening degree, it seems impossible, if the Supreme know please tell, I learn to learn
Electric switch valve is powered that the valve is turned off to close off, the switch is controlled by the voltage or current to adjust the valve opening, he needs a change in the amount.
Valve + adjustable type of electric equipment (sub-switch type and adjustable type two) can be achieved, but you need the kind of 4 ~ 20mA feedback signal with the intelligent integrated Denso, you can access the local operation box and remote computer control, Domestic quality is better Tianjin two links, Yang price more reasonable, and then your point is Chongqing, Sichuan, Rui Ji.
