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

Answer / msn raju

Because gas want to went to atmosphere upside always and liquid always downside

Answer / r.govindasamy

gas will not condensate so txr connected above fluid
line.Butsteam line steam will be condnsate.so txr connected
below fluid line.

Answer / trideep

According to the charcter of gas in fluid mechanisam theary, it has no size and wont accumulate at the desired place/ tank if you say.. In case of liquid vice versa....
