Instrument Hook Up Drawings

Just looking thru' some hook ups for a project revamp and those supplied for Instrument Pressure devices are labelled for both "gas/ liquid" with no real distinction.

In my opinion, separate hook ups should be drawn for gas and liquid showing 1:12 or 12:1 impulse gradient as well as the Material Take Off, am I right?

Also when is a Hydro Carbon classed as gas or liquid service?

Best Regards & a Happy New Year
