采用全自动流量控制，选用先进的流量控制技术，配合智能流量控制算法，实现流量的全自动控制，在检定过程中，只需设定当前流量点，启动系统检定，系统会自动进行流量控制，其控制曲线达到控制要求，提高系统控制精度。- This paper use automatic flow control and select advanced flow control technique with intelligent flow control algorithm. It implements full automatic control of the flow, in the process of verification, only need to set the current flow point and start the system, it will control flow automatically. The control curves meet control requirements, and improve system control precision.
