Pressurewhat pressure? - Coastal Flow

pressure ? Among the most misunderstood and misapplied terms used in natural gas measurement are pressure Base, Atmospheric pressure , Gauge pressure , and Absolute pressure . Not only are these expressions easy to confuse, when their values are incorrectly applied within the flow equation, measurement error is introduced and oftentimes that error can be severe. Understanding these fundamental terms and how they are applied is of vital importance to those involved in every phase of gas measurement, accounting, and regulatory reporting. The following is a brief definition for each of these terms: pressure Base is the pressure at which a volume occupies one standard cubic foot (scf), as defined by contract, expressed in pounds per square inch absolute (psia).
