Using a pitot tube if flowmeter is not working

Then, the standard differential pressure at this point is fitted from the wind tunnel calibration curve of the probe, and the fluid flow is calculated according to the standard differential pressure. The pitot tube flowmeter inserts the probe into the center of the pipeline, the incoming direction of the total pressure hole to the positive fluid, the outgoing direction of the static pressure hole to the positive fluid, and the difference between the total pressure and static pressure is the measured differential pressure in the center of the pipeline. Such as: Test and detection of aircraft wind tunnel, aerodynamic test of aircraft engine, velocimeter rod of aircraft flight speed, etc. Pitot tube principle has been widely used in aerospace industry for a long time.

Pitot tube flowmeter is a differential pressure flowmeter that uses pitot tube principle to extract the fluid velocity in the center of the pipeline (total pressure static pressure = dynamic pressure) and then convert it into fluid volume flow and mass flow.
