Computation and Measurement Model about Gas Flux in the Pipeline Based on Vapour Pressure Equation

基于水的蒸汽压方程下 ,建立工况下管道煤气流量新的计量模型 ,由该计量模型的应用可知 ,该模型中不再要求建立管道煤气中不同温度下所对应的水蒸汽饱和压力数据库 ,从而可以大大简化管道煤气流量计量软件 。

A new model of computation and measurement about gas flux in the pipeline at different work cases based on vapour pressure equation is established. Some messages from the application of the model can be gotten that a database about water vapour saturated pressure in the gas pipeline based on different temperature need not be established, that will greatly simplify the software of computation and measurement about gas flux in the pipeline and will quickly and truly realize computation and measurement about gas flux in the pipeline in real time and on line at the design range of flowmeter.
