10、nstituteFOREWORDChapter 5 of the API Manual of Petroleum Measurement Standards (API MPMS) pro-vides recommendations, based on best industry practice, for the custody transfer metering ofliquid hydrocarbons. The various sections of this Chapter are intended to be used in con-junction with API MPMS Ch
11、apter 6 to provide design criteria for custody transfer meteringencountered in most aircraft, marine, pipeline, and terminal applications. The informationcontained in this chapter may also be applied to non-custody transfer metering.The chapter deals with the principal types of meters currently in u
12、se: displacement meters,turbine meters and Coriolis meters. If other types of meters gain wide acceptance for themeasurement of liquid hydrocarbon custody transfers, they will be included in subsequentsections of this chapter.Nothing contained in any API publication is to be construed as granting an
