AFMT and differential pressure transmitter are often being used in the measurement of flow. With several pressure detecting holes on the AFMT, we can get the average of the flow inside the duct  and improve the problem happened in the flow measuring where disturbance occurs when there’s no adequate space inside the straight inlet.
AFMT is a probe we inserted into the duct(along with the whole diameter) to measure the flow. When the probe encounters the flow, will sense and get the average total pressure P1 in windward side and static pressure P2 in leeward. AFMT then gets the flow velocity by measuring the difference between total pressure and static pressure(i.e.) dynamic pressure(∆P) and flow average velocity(V).
