        #description: "The object of this Document is to define and describe the proper measurement of any flow required or recommended by any of the Performance Test Codes. Flow measurements performed as specified herein satisfy the requirements of all revelant ISO flow measurement standards in effect at the time of publication. This Document describes the techniques and methods of all flow measurements required or recommended by the Performance Test Codes. Newer flow measurement techniques of comparably high accuracy are included to provide alternative flow measurements for special situations in which deviations from the requirements of a code are agreed to be necessary. This is a supplementary Document that does not supersede the mandatory requirements of any code unless such an agreement has been expressed in writing prior to testing. This publication is issued with an automatic addenda service. All addenda service publications are issued in loose leaf format to facilitate later insertion of replacement pages which incorporate the latest approved changes to the standard. Purchasers may wish to purchase a binder from ASME (ASME Binder), but the publication will also fit a standard three ring binder. Details on the specifics of the addenda service are as follows:"

        #description: "This standard applies only to the steady flow of single-phase gasses and gas mixtures and applies only to bellmouth inlet flowmeters in which the flow remains subsonic throughout the measuring section and the flow is steady of varies only slowly with time. It also addresses procedures by which calibration of the device can be made to allow for application with consistent conclusions and with known limits of uncertainty. Bellmouth inlet flowmeters should be used only within the limits for which a given unit is tested, or if additional uncertainty can be tolerated, over a range within which extrapolation is reliable. This Standard outlines the general geometry and method of use of bellmouth inlet flowmeters to determine the mass or volumetric flow rate of the gas or gas mixture flowing through the device. It also gives necessary information for calculating the flow rate and its associated uncertainty. A bellmouth inlet flowmeter is a device that provides flow conditioning and flow measurement whose inlet is located or positioned in a large reservoir or supply source. The reservoir can be outside ambient, room or plenum conditions depending on the application. The bellmouth inlet flowmeter is also referred to as an airbell, nozzle with zero beta ratio, borda tube, etc. Typically geometry consists of a convergent inlet followed by a constant throat area. This flowmeter is a differential pressure type device that allows determination of the flow rate from the differential pressure between the total pressure and static pressure at a single specified axial location in the constant area throat of the bellmouth. Key Features: Benefits: Fundamentals and usage Used extensively in aerospace test facilities for gas turbine engines for flow conditioning and flow measurement. Inlet flare design and measurement considerations are provided. Non-mandatory appendix provided for the development of calculation with derivation. Instrumentation Options for instrumentation methods are provided and the impact on calculation and calibration are discussed. Also provided are total pressure, static pressure, and total temperature measurements and how they must be consistent in calibration and use. Calibration and uncertainty Various methods for developing NIST traceable results for calculated air flow rate in velocity, volumetric and mass flowrates are discussed. Overview of boundary layer growth and other contributors to calibration results are considered. Computational fluid dynamics (CFD) analysis is mentioned as significant impact to calibration result. Also provided is an overview of the approach for developing uncertainty statement (data quality) with practical steps for determination. Intended for engineers and other users of gas-flow measurement devices in such industries as energy, automotive and aerospace."

        #description: "This standard applies only to the steady flow of single-phase gasses and gas mixtures and applies only to bellmouth inlet flowmeters in which the flow remains subsonic throughout the measuring section and the flow is steady of varies only slowly with time. It also addresses procedures by which calibration of the device can be made to allow for application with consistent conclusions and with known limits of uncertainty. Bellmouth inlet flowmeters should be used only within the limits for which a given unit is tested, or if additional uncertainty can be tolerated, over a range within which extrapolation is reliable. This Standard outlines the general geometry and method of use of bellmouth inlet flowmeters to determine the mass or volumetric flow rate of the gas or gas mixture flowing through the device. It also gives necessary information for calculating the flow rate and its associated uncertainty. A bellmouth inlet flowmeter is a device that provides flow conditioning and flow measurement whose inlet is located or positioned in a large reservoir or supply source. The reservoir can be outside ambient, room or plenum conditions depending on the application. The bellmouth inlet flowmeter is also referred to as an airbell, nozzle with zero beta ratio, borda tube, etc. Typically geometry consists of a convergent inlet followed by a constant throat area. This flowmeter is a differential pressure type device that allows determination of the flow rate from the differential pressure between the total pressure and static pressure at a single specified axial location in the constant area throat of the bellmouth. Key Features: Benefits: Fundamentals and usage Used extensively in aerospace test facilities for gas turbine engines for flow conditioning and flow measurement. Inlet flare design and measurement considerations are provided. Non-mandatory appendix provided for the development of calculation with derivation. Instrumentation Options for instrumentation methods are provided and the impact on calculation and calibration are discussed. Also provided are total pressure, static pressure, and total temperature measurements and how they must be consistent in calibration and use. Calibration and uncertainty Various methods for developing NIST traceable results for calculated air flow rate in velocity, volumetric and mass flowrates are discussed. Overview of boundary layer growth and other contributors to calibration results are considered. Computational fluid dynamics (CFD) analysis is mentioned as significant impact to calibration result. Also provided is an overview of the approach for developing uncertainty statement (data quality) with practical steps for determination. Intended for engineers and other users of gas-flow measurement devices in such industries as energy, automotive and aerospace."
