I have two differential sensors and in my experiment I wish to measure the air pressure from below and on top of the ball that is levitated by air. These are my 3 possible setups. Considering the 3 setups what is the best and most accurate way of measuring $P_1$ and $P_2$ ?
Utilizes only one differential sensor that measures the dynamic pressure from above the ball and below the ball.
Utilizes two differential sensors and a Pitot tube to measure static and dynamic pressure and get its difference.
Utilizes two differential sensors, with a similar concept as that of a pitot tube and gets the difference between the dynamic and static pressure from the top and below the ball.
