Humidification type gas flow measuring device and method

The invention discloses a humidification type gas flow measuring device and method.The output end of a humidifier is communicated with the side face of a gas pipeline, the gas pipeline is used for circulating to-be-measured gas, and two temperature and humidity measuring units are used for measuring the dry-bulb temperature and the relative humidity of the to-be-measured gas before and after humidification of the humidifier respectively; the processing unit is used for calculating the flow of the to-be-measured gas. The measuring probes of the two groups of temperature and humidity measuring units are arranged in the gas pipeline, the surfaces of the measuring probes are exchanged with air, the temperature and humidity parameters of gas exchange are monitored through the measuring units, the gas flow of the pipeline is calculated, the implementation method is simple, and the accuracy is high. 本发明公开一种加湿型气体流量测量装置及方法，加湿器的输出端与一气体管道的侧面连通，所述气体管道用于流通待测气体，两组温度和湿度测量单元分别用于测量所述加湿器加湿前后待测气体的干球温度和相对湿度，处理单元用于计算待测气体的流量。本发明将两
