how to install Differential pressure transmitter in gas
line.i need transmitter down side.
Answer Posted / www.islamqa.com
Bharathi is right, we have to use "condensation pot"
# Actually the gas is "self venting" and the instrument
mounting should be above the pipeline in order to avoid
vapor condensation which cuase fault reading.
# For liquid service the instrument mounting should be
below the pipeline as the liquid is "self draining".
# If we want to mount the instrument below the pipeline in
gas service we should use "condensation pot" and the
operator should drain it regularly to avoid fault reading.
# In steam service we use the condensation pot also and it
should be fully filled with water and its mounting should
be in the same pipeline level and the instrument itself
will be below the pipeline, this link indicte the situation:

the aim of water filling is to provide a solid motion
transfer in order to have a good accuracy.
