AGA XQ2402

This manual provides instructions related to the principle of operation, typical operating characteristics, and applications of Orifice Meters as well as installation, calibration, testing, and maintenance procedures, and computations used in the calculations of flow for the measurement of natural gas. Typical applications include measuring single-phase gas flow found in production, process, transmission, storage, distribution, and end-use gas measurement systems.

This manual also provides practical formulas for reference and training of new entrants to the industry, as well as measurement office and non-technical individuals unfamiliar with natural gas orifice meter measurement. It is intended for use in conjunction with API MPMS 14.3/AGA Report No.3 – Orifice Metering of Natural Gas and Other Related Hydrocarbon Fluids, API MPMS 21.1-Flow Measurement Using Electronic Metering Systems-Section 1: Electronic Gas Measurement, and technical manuals produced by meter manufacturers. The general guidance provided in this manual is not intended to replace or supersede the meter design-specific information provided by the manufacturer. This manual is not intended for use as a standard and is not intended for reference in a tariff or other regulatory documents.
