API MPMS 13.2-1994 Manual of Petroleum Measurement Standards Chapter 13 - Statistical Aspects of Measuring and Sampling Section 2 - Methods of Evaluating Meter Proving Data (FIRST EDITION; ERTA: October 2015)
Chapter 13.2 will address procedures for evaluating any meter's performance where meter proving factors are developed in accordance with Chapter 12.2. The data in examples used in this chapter are intended to be typical of custody transfer operations of low-vapor-pressure fluids using dis-placement or turbine meters in accordance with Chapters 4@ 5@ and 6 of the Manual of Petroleum Measurement Standards. However@ the procedures in Chapter 13.2 can be used for non-custody transfer metering applications and for custody transfer metering of high-vapor-pressure and gaseous fluids where meter proving data are available. Procedures and examples are given for analyzing the random uncertainties associated with meter proving data (see note). Procedures and examples are also given for evaluating and controlling trends in meter factors with control charts and control logs to ensure that meter factor variations exhibit a random nature that results in the propagation of a lower average uncertainty in measurements with time and throughput. Note: Uncertainty computations are Nord on procedures given in Chapter 13.1 of the Manual of Petroleum Measurement Standards. Since no single document can cover all of the statistical procedures and applications being practiced@ procedures other than those appearing herein may be used. Alternate statistical procedures are not expected to duplicate the computational values provided by procedures in this chapter. However@ alternative procedures should achieve the same purpose intended by the procedures given herein. When alternative statistical computational procedures are to be used and affect metered quantities@ panics directly involved with the metering operations should be notified prior to their implementation. Some of the procedures in Chapter 13.2 are suitable for hand calculations and graphs employed by field personnel. These procedures are discussed and illustrated in 13.2.5 of this chapter. However@ the statistical evaluations and control charts are generally too rigorous for manual field computations@ and computers should be employed. The statistical procedures in this document may serve as a guide for developing software for computer applications.
