I am installing magnehelic gauges to measure pressure drop across some filter banks. I know it's best to use static pressure tips on each side of the filters, but is it okay to just stub out the tubing on each side. Also is it best to run the tubing to the middle of the filter bank or can you just run it a few inches into the filter section? Most installations I have seen in the past have been just the tubing run about 3 to 10 inches into the unit.
Thanks for any advise.
