We have standard diagrams for flow measurement( DP type ) Installation,but how should we determine whether Dry Gas or Wet gas is being used,coz installation scheme will be varied in both the installation.
Depending on the type of flowmeter you are using, the readings may be different between measuring dry or humid gases.
So therefore you will need to measure the humidity to correct your readings, that is if the gas composition is going to change and if the flow measuring principle you are using takes any notice of the humidity....
