摘要: 随着环保部门及企业对脱硫烟气流量准确性的要求越来越高，部分企业流量计安装位置无法准确反应企业的实际工况，而采用网状测量烟气流量可以较好的解决此类问题。根据各测量截面尺寸的大小、直管段长短等因素确定测量点数，将许多个测量点等截面有机地组装在一起，测得截面的平均速度，然后计算出风量。详细的介绍了网状测量烟气流量在污染源自动监控烟气流量测量的优势，原理，并就该技术的应用前景进行了分析和展望。

Abstract: As the environmental protection department and the enterprise demand for desulfurization of flue gas flow accuracy is higher and higher, some enterprises flowmeter installation position can't correctly reflect enterprise's actual working condition, and flue gas flow measurement by mesh can better solve such problems, according to the size of each measurement section size, length of straight pipe and other factors determine the measuring points, such as many points section organically together, measured the average velocity of cross section, and then calculate the air volume. Detailed introduces the network measurement of gas flow in the pollution source automatic monitoring the advantage of the flue gas flow measurement,
