If the impulse line connected to the low side of the differential pressure instrument is filled with a suitable fluid, it's called (wet leg).
If the impulse line is empty, it's called (dry leg).
Dry leg & Wet leg is a technique used in differential pressure measuremnt for 2 main reasons:
1 - We use (wet leg) to prevent the dangerous fluid from harming the sensitive instrument.
2 - In closed tank application, we use (wet leg) to prevent vapour condenstion due to temperature variation, so we get a stable/accurate measurement.
Good Luck
