With the manometer arranged in this way, does it measure the dynamic pressure of the gas? !

As shown in the figure. 2 pressure measurement tubes, located at the tube wall and at the center of the tube respectively. Connect the wind pressure sensor. The differential pressure measured in this way is the dynamic pressure of the gas, right? Dynamic pressure = Total pressure - Static pressure. Or is dynamic pressure unmeasurable (there are such claims online)? I would appreciate some guidance from experts, thank you!
After all, without flow, where can there be a pressure difference? No
Will there be a pressure difference measured in this way? Is differential pressure dynamic pressure?
Give me an accurate **, we’re going to use this setup now.
Are you using a pressure transmitter or a differential pressure transmitter?
Just use a U-tube manometer
Of course, it’s the dynamic pressure that is measured; static pressure cannot be measured in essence. It can only be obtained by subtracting the dynamic pressure at a certain point from the total pressure of the fan. That is, only when the fan is running and the outlet is completely closed is it possible to measure the static pressure under such conditions; at that time, the static pressure is equal to the total pressure.
