工业计算机在管道气体流量计量系统中的应用

The Application of the Industrial Computer in the Measurement System of Pipeline Gases Flow Capacity

在管道气体（空气、蒸汽、燃气）流量计量中，以传统节流装置为基础、工业计算机为核心进行信号采集计算、数据管理、传送、打印，一改传统的计量系统设计方式，提高了系统设计精度，工作稳定性更强，更便于管理。本文详尽给出了其设计思想、管理方式，并介绍了使用结果。

On measuring the flow capacity of the pipeline gases(air, steam and gas), based on the traditional throttling devices, industrial computers are used as the main tools in signal collecting and calculating, data man- agement,data delivery and data printing. Traditional design of the measurement system is changed and the precision is greatly improved. The new system works much more steadily and is easier to manage. The essay tells the design ideas, management ways and operation results in details.
