MASS METERS FOR GAS MEASUREMENT Class # 1200

摘要

Since the early 1977,Coriolis meters have gained worldwide acceptance in gas,liquid,and slurry applications with an installed base of well over a million units.Since the early 1990s Coriolis meters have rapidly gained acceptance in gas applications with over 100,000 meters installed worldwide.Principal gas applications for Coriolis meters include fiscal transfer of valuable process gases such as ethylene,oxygen,and hydrogen,utility gases such as natural gas,and reactor feed gases such as hydrogen,ethylene,ammonia,and chlorine.Coriolis meters offer improved measurement accuracy over wide turndowns and with less installed uncertainty due to swirl and flow profile effects.Industry acceptance,knowledge,and experience with Coriolis meters in natural gas measurement has been signified by the publication of the first edition in 2003,followed by the second edition in 2013 of AGA Report Number 11(AGA 11),Measurement of Natural Gas by Coriolis Meter.
