In 2021, China launched its national carbon market. To enhance the accuracy of carbon trading, it is essential that carbon emission data are measurable, reportable, and verifiable. Against this backdrop, online monitoring systems for flue gas have gained significant attentions as a method of quantifying carbon emissions. The basis for the effective work of continuous emission monitoring systems is the accurate measurement of flue gas flow. However, the challenge in accurately measuring flue gas flow rates is significantly heightened by the large size of power plant chimneys and the complexity of the gas flow characteristics within them. This paper focuses on analyzing the current research status of Pitot tube flowmeters and ultrasonic flowmeters in large-scale duct flow measurement, and provides a detailed introduction to gas flow measurement technologies for large-scale ducts. Additionally, it introduces an independent flow measurement method, namely the tracer gas dilution method, and discusses its current development and potential as a flow calibration method.
