Pressure will be added up a bit more, see its detail:
1. Suppose,you want to install a pressure transmitter 10
meter below of pipe line.
2. Density of methane (Examlpe) 0.656 kg/m3 at 25C.
3. your pressure transmitter will show (10 x 1000 x0.656 =
6560mm) 6569 mm of water pressure more.
4. Suppose gas pressure is 20Kg/cm2, then due to this
elevation, transmitter will show 20.66Kg/cm2

Answer / narayan

it will not give correct pressure, since natural gas condense in the lower side, actual pressure will be added with this head pressure of liquid, hence it will not give the actual pressure of gas
so transmitter should be installed above the pipe line, to measure exact pressure of NG

Answer / karthick
