有关湿气测量的几个常见问题

湿气组成具有一定的特殊性，其存在形态、物性参数等经常不能达到标准孔板所要求的技术条件，从而导致较大的湿气测量误差。根据现场实际，对影响湿气测量的超压缩系数计算、相对密度变化、孔板安装条件等因素进行探讨，并给出了现场测试结果。

Common Problems With Wet Gas Measurement

With the composite characteristics of wet gas, its forms of existence and physical parameters often fail to conform to the technical specifications of standard orifice plates, thus causing greater metering errors. In this paper, an explorative discussion is made of such factors as computation of super-compressibility factors, change of relative density, and condition for installing orifice plates that may affect the measurement of wet gas. The results of field test are given.
