Principle and Selection of Air Velocity Flow Transmitter in Duct

Flow Rate is the total volume of air flowing through the section in unit time. The accurate unit air volume can be obtained by multiplying the average velocity on the cross section by the cross section area. 

Principle of Pitoty Type Air Flow Velocity Transmitter

However, it is difficult to measure the average wind speed on the cross section, which is related to the medium of the fluid, atmospheric pressure and the roughness of the pipe wall. The difference between the maximum value and the minimum value is several times, and the flow distribution is not even. Therefore, the error of calculating the unit air volume is very large by measuring the air speed at a certain point multiplied by the cross-sectional area. The selection, installation and application of air velocity flow transmitter are more like a specific project. The selection is unreasonable, the cost is high, and the accuracy is poor.
