Why can a DP flowmeter be used for gas but not liquid?

Acceptable uncertainty in quantity transferred determines flowmeter selection

Q: I'm interested to know why orifice differential pressure (DP) flowmeters aren't used in liquid metering systems (for custody transfer purposes), whereas they're widely used in gas metering systems? What makes an orifice flowmeter a viable, cost-effective choice for gas metering systems only?A.
