This testing protocol provides the minimum requirements for documenting performance testing of an inline multiphase flow meter under controlled flowing conditions in a flow loop facility. Completion of the testing protocol is not a calibration and does not replace field testing and validation.
This testing protocol documents the method for testing the performance characteristics of multiphase flow meters used in production allocation. The testing protocol includes a listing of parameters affecting the performance of the devices, a description of the tests required, requirements for the test facility, a data reporting format, and an uncertainty determination methodology.
The following are objectives of this testing protocol:
— Provide documented performance characteristics and parameter sensitivity of the multiphase meter under controlled fluid properties and flowing conditions over a defined operating range with a standardized reporting format.
— State the assumptions of the operating and installation conditions for which the stated uncertainties apply.
Dynamic testing enables the evaluation of performance (and factors influencing performance) of a multiphase flow meter (MPFM) technology/type/model across a clearly defined operating range under controlled conditions.
Performance testing of a multiphase flow meter is a critical step in validation of the flow models and the fluid models that are used to measure multiphase flow. A multiphase meter will typically contain several of these models in order to address the challenge of measuring individual phase flow rates within a range of flow regimes, operating velocities, and fluid types.
