It's been a while since I've done the calculation but to determine the airflow velocity (rough measurement only) do I use the following formula:
(Differential pressure + ((Differential pressure)^0.5))/2
Background:
I bought a 0-5 psi differential pressure sensor and an IC that converts the raw mv signal from the sensor into a 4-20mA signal, which I then send back to my PLC. I'm trying to get a rough representation of the airflow through a pipe. The pipe size is 1" and the orifice that I had my maintained team fab up is 1/2 inch.
