When wet leg design is implemented, which side of the differential pressure transmitter (DPT) is connected to the wet leg? (+) or (-)? Does the density of the filling fluid have to be taken into consideration, and if yes, how (heavier or lighter than process fluid)? If the filling fluid is condensate (steam level measurement), then which side of DPT is connected to the wet leg? If it is connected vice versa, is it wrong?
