Keep your fiscal and custody Coriolis metering points in compliance with updated API MPMS Ch. 5.6 guidelines 

The American Petroleum Institute (API) has been creating and maintaining standards for the oil and natural gas industry globally since 1924(API). Having equipment that is built to proper API specifications and running your facilities according to API standards can help minimize safety and environmental dangers in your plant and allow you to operate efficiently. 

In December of 2021, API finalized MPMS Ch. 5.6 “Measurement of Liquid Hydrocarbons by Coriolis Meters; Second Edition”. This revision includes substantial normative operating changes that relate specifically to the effect of pressure on Coriolis mass flow measurement for fiscal and custody metering purposes. It sets the necessary guidelines for determining when and how pressure compensation must be applied in order to stay in compliance with API MPMS guidelines. 

Operating according to API standards can be a good practice for natural gas and oil operators,  when no national standard or governing body exists for your region.
