Description / Abstract:

These specifications apply to axial-flow turbine flow meters for measurement of natural gas, typically 2-inch and larger bore diameter, in which the entire gas stream flows through the meter rotor. Typical applications include measuring single-phase gas flow found in production, process, transmission, storage, and distribution and end-use gas measurement systems. Typical use is the measurement of fuel grade natural gas and associated hydrocarbon gases either as pure hydrocarbons or as a mixture of pure hydrocarbons and diluents. Although not within the scope of this document, turbine meters are used to measure a broad range of fluids other than natural gas.

This report does not address the characteristics of electronic pulse signal generating devices within or attached to the meter, although it does address the use of their outputs.

Also not addressed are the characteristics of mechanical or electronic instruments that convert meter outputs from line conditions to base conditions. However, Appendix B does contain the equations establishing the mathematical basis for the conversion process. Although these equations appear in this report, they may be used to convert volume registered by any type of meter.
