Pitot tube is a tubular device that measures total air pressure and static pressure to determine air flow velocity. It is widely used in scientific research, production, teaching, environmental protection and clean room, mine ventilation and energy management departments. Measure the air velocity in the pipe and the air velocity in the flue of the furnace, and determine the flow rate after conversion. The velocity of the liquid in the pipe can also be measured. The pitot tube is used to determine the flow rate and flow rate. The pitot tube is convenient, fast and highly accurate. It is a classic measurement method.
