Title
Manual of Petroleum Measurement Standards Chapter 14Natural Gas Fluids Measurement Section 3Concentric, Square-Edged Orifice Meters Part 2Specification and Installation Requirements
American Petroleum Institute
Publication Date:
Apr 1, 2000
Scope:
Construction and Installation Requirements
This document outlines the various design parameters that must be considered when designing metering facilities using orifice meters. The mechanical tolerances found in this document encompass a wide range of orifice diameter ratios for which experimental results are available. In several sections of this document, tolerances for the mechanical specifications have been changed relative to previous editions. In particular, this revision includes a change to the installation requirements (meter tube lengths). This change reduces the uncertainty attributable to installation effects to a magnitude smaller than the uncertainty of the database supporting the Reader-Harris/Gallagher (RG) equation and, therefore, should not affect the uncertainty reviously defined for that equation.
This document does not require upgrading existing installations. If the meter installations are not upgraded to meet this current standard, however, measurement bias errors may exist due to inadequate flow conditioning and upstream straight pipe lengths. The decision to upgrade an existing installation shall be at the discretion of the parties involved.
