The AFP series Pitot tube is a supporting measuring instrument used for ventilation work in coal mines, metallurgy, railways, construction, etc., to measure the wind speed at any point in the mine ventilation network.

In scientific research, production, education, environmental protection, clean rooms, mine ventilation, and energy management departments, the Pitot tube is commonly used to measure the wind speed in pipelines and the airflow velocity in furnace flues. Through conversion, the flow rate can be determined. It can also measure the flow velocity of water in pipelines. Using the Pitot tube for speed measurement and flow rate determination has a reliable theoretical basis, is convenient and accurate to use, and is a classic and widely used measurement method. Additionally, it can be used to measure fluid pressure. It can also be applied for performance evaluation of main mine fans and auxiliary fans, measurement of flow rates in mine gas extraction pipelines, and determination of reference wind speed in air duct calibration for anemometers.
