working principle

Align the pitot tube with the airflow direction, with the negative end facing away from the airflow direction. When the flue airflow passes through the positive and negative nozzles of the pitot tube, a pressure difference will be generated. The microprocessor calculates the static pressure, flow rate, and air volume based on the collected dynamic pressure, total pressure, and smoke temperature signals, and then automatically calculates the * flow rate based on the input values of atmospheric pressure, humidity, pipeline cross-sectional area, and other parameters.
