What Happen If I Install My Pressure Transmitter Below The Elevation Of Pipe In Natural Gas Service?

Pressure will be added up a bit more, see its detail:

  • Suppose,you want to install a pressure transmitter 10 meter below of pipe line.
  • Density of methane (Examlpe) 0.656 kg/m3 at 25C.
  • your pressure transmitter will show (10 x 1000 x0.656 = 6560mm) 6569 mm of water pressure more.
  • Suppose gas pressure is 20Kg/cm2, then due to this elevation, transmitter will show 20.66Kg/cm2
