Pressure Transmitter

If vapours means a gas, then yes.

Condensate or liquid, or liquid droplets in the line will tend to drop to the bottom of an impulse line below the tapping point and collect there.

Gas pressure measurements are done at an elevation above the tapping point/line in order to keep the impulse line free of liquid.

..so the only individual that can answer the question is the one looking at either the location of the proposed installation, looking at the P&IDs and general arrangent drawings, or looking at the instrument hook-up drawing for the instrument in question. It's a bit difficult to see any of those things from here.
