Answer / vinod patil

In gas connection to avoid liquid traps in gas flow measurement, as liquid is more denser it will remain below hence gas tap connections are given above.
And in liquid to avoid gas traps in liquid flow measurement, as gas is less denser it will be in upper area of pipe, so tap are given at bottom.

Answer / guest

Gas is lighter than liquid ie the specific gravity is less
than liquid.
