On-line Measurement System for Gas Flux in the Pipeline Based on Vapour Pressure Equation

E Jia-qiang,SHI Zhang-ming,LIU Chun-yang(School of Energy and Power Engineering, Central South University, Changsha,Hunan 410083, China)  
In order to solve the gas measurement problems, such as low precision or difficult measurement, a new model of measurement about gas flux in the pipeline at different work cases based on vapour pressure equation is developed. The application of the on-line measurement system shows that a database about water vapour saturated pressure in the gas pipeline based on different temperatures is not needed, which would greatly simplify the software of measurement about gas flux in the pipeline and will quickly and truly realize measurement about gas flux in the pipeline in real time and on line at the design range of flowmeter.
