Air Flow Instrument Location
(OP)
I know that typically air flow dP cells are mounted above the flow element. What do I do if I have to mount the dP cell below the flow element?

RE: Air Flow Instrument Location
You could try putting in a "drip loop" (essentially just a U-shaped loop of tubing hanging below the level of the cell on each tube run). Checking the loops for condensation and draining them periodically (e.g. thru a purposely installed valve or drain fitting) will help; some people put a very small pinhole in the bottom of the loop tube to drain away condensation, but this causes some concern over accuracy at low speeds, and you have to make sure the water drips don't go somewhere you don't want them to.

Not only do DP cells work best above the flow elements but the connections should not have any "traps".
