This protocol is des

37、igned to supply industry with a comparable description of the capabilities of flare gas meters for gaseous fluid flow measurement. The following are objectives of this Testing Protocol. Provide information about relative performance characteristics of the flare gas meter under a standardized testing

38、 protocol over an expected operating range with a standardized reporting format. (See 6.1 for determination of the expected operating range.) Facilitate both the understanding and the introduction of new technologies. Provide a standardized vehicle for manufacturers to validate the meters performanc

39、e. Quantify the uncertainty of these devices and define the operating and installation conditions for which the stated uncertainties apply.To accomplish these objectives, in addition to the base testing requirements defined in this document, the end user should define any application specific requir

40、ements not covered by the base testing requirements such as the following. Expected operating range of the meter where this exceeds the base testing requirement operating range. Upstream flow disturbances not addressed by the base testing requirements. Criteria needed to comply with regulatory requi

41、rements.When specifying additional testing requirements, the end user should insure that all parameters affecting the meters performance are identified, but not limited to, items described in Section 6.The facility selected to perform the tests has to be able to correlate the test fluid to the fluid

42、s to be measured at the expected process conditions.Examples of flare gas meters covered in this standard include, but are not limited to differential pressure flow meters, optical meters, thermal flow meters, ultrasonic flare meters, vortex shedding meters.If a meter has been tested under another A

43、PI MPMS Chapter 22 testing protocol that covers the entire expected operating range for this application, testing the influence parameters listed in Section 5 and the ranges defined in 6.4, then additional testing is optional. Reporting and testing protocols for test facilities are included to ensur

44、e that the performance characteristics of each meter are compared with identical conditions as set forth in this standard.vi1Testing Protocol for Flare Gas Metering1 ScopeThe scope of the standard is to describe a testing protocol for flare gas meters. This includes a discussion of the testing to be

45、 performed, how the test data should be analyzed, and how an uncertainty is determined from the testing of the meter. The scope does not include the general guidelines to flare gas metering that are covered under MPMSChapter 14.10.2 Normative ReferencesThe following referenced documents are indispen
