What is ISO 21354 about?
ISO 21354 is an international standard on fluid flow that discusses the various parameters involved. ISO 21354 establishes a common basis for, and assistance in, the classification of applications and multiphase meters, as well as guidance and recommendations for the implementation and use of such meters.
The so-called in-line multiphase flow meters (MPFMs) that directly measure the oil, water and gas flow rates, as well as the partial- and full-separation MPFMs are the main focus of ISO 21354
Conventional two- or three-phase separators are not included in ISO 21354. Only limited reference is made to wet-gas meters since although wet-gas flow is a subset of multiphase flow, wet-gas measurement is covered by ISO/TR 11583 and ISO/TR 12748
Who is ISO 21354 for?
ISO 21354 on measurement of multiphase fluid flow is beneficial for
- Manufacturer of multiphase flowmeters
- Oil and gas production companies
- Research laboratories
Why should you use ISO 21354?
Multiphase flow meters (MPFM) are devices used for the measurement of the flow of oil, water and gas in a multiphase flow.
ISO 21354 provides guidance on multiphase flow, aims of multiphase flow measurement, production envelope and installation design guidelines, performance specification, testing, calibration and adjustment, field installation and commissioning, verification during operation
ISO 21354 is intended to serve as guidance for users, designers and manufacturers of multiphase metering systems. ISO 21354 can also serve as an introduction to newcomers in the field of multiphase flow measurement, with the definition of terms and a description of multiphase flow in closed conduits being included. ISO 21354 enables the user to compare different meters and evaluate their suitability for use in specific applications.
