从流体经过孔板产生信号出发，到在流量积算仪上显示流量，用四象限信号转换图直观地剖析了信号的多次转换，重点阐明了其中的非线性转换。

From the flow signal generated by orifice to the display on flow totalizer, the multiple conversions of signals are dissected directly perceived through four quadrants signal conversion diagram.

重点阐述了在此基础上设计的VX3000流量积算记录仪的流量积算、流量显示、记录、报表和联网功能。

Firstly, the functions, including flow totalizing, flow display, record, report and networking, of the VX3000 flow totalizing recorder which is designed on above basis are presented emphatically.

流量组合框里的传感器、I/O、压力是用来显示分析仪上样品气和载气流路。

The Flow association represents which sensor on which I/O Board or Pressure Board should be used to view the sample flows and carrier flows in the analyzer.
