Answer / imran mansuri

For gas and vapor flows, it is important that
no stray liquid droplets collect in the impulse lines
leading to the transmitter, incase vertical liquid
column begin to collect in those lines and generate an
error-producing pressure For liquid flows, it is
important that no gas bubbles collect in the impulse lines,
or else those bubbles may displace liquid
from the lines and thereby cause unequal vertical liquid
columns, which would (again) generate an
error-producing differential pressure.
In order to let gravity do the work of preventing these
problems, we must locate the transmitter
above the pipe for gas flow applications and below the pipe
for liquid flow applications
