I am installing a dp transmitter along with a temp probe and a static pressure transmitter and I am trying to figure out the best way to calculate the flow rate of a gas in a control logic using ladder programming. I was wondering if anyone knows of a place where i can look at examples of that logic? Does rockwell offer examples of it different logic? thanks!
 
ASME PTC 19.5 is the most authoritative guide to flow measurement. The equation relating differential pressure to flow will vary based on the primary element - pitot tube, orifice, flow tube, etc.
