CD3(A)型皮托管流量计在瓦斯气体输送管道中的应用

Application of CD3(A) Pitot Flowmeter in Gas Pipeline Transportation

便携式CD3(A)型皮托管流量计用于测量煤矿瓦斯抽采管道或者天然气、页岩气输送瓦斯气体管道内的气体流量、温度、绝对压力、流速及环境大气压等参数;该仪器基于皮托管原理基础上研发设计,能够实时测量、显示、存储及查询管道气体流量、流速、介质压力、介质温度、环境大气压等参数,支持数据导入导出,正、反双向都可测量。简述了流量计的工作原理和现场适应性应用。

Portable CD3（A）type pitot tube flowmeter is used to measure parameters such as gas flow, temperature, absolute pressure, flow rate and environmental barometric pressure in gas extraction pipeline of coal mine or gas transportation in natural gas, shale gas pipeline. The instrument is based on the pitot tube principle to research and design, and it can in measure, display, store and query parameters such as gas flow rate, flow velocity and pressure of medium, medium temperature, environmental barometric pressure in pipeline in real time, and can support data import and export, forward and reverse bi-directional measurement. The principle of flowmeter and the application of field adaptability are briefly described.
