(a) This Standard applies to: (1) axial full-flow turbine meters with mechanical and\/or electrical outputs whose rotating member is driven by a compressible fluid; (2) the measurement of gas by a turbine meter; the meter’s construction, installation, operation, performance characteristics, data computation and presentation, calibration, field checking, and other related considerations of the meter. (b) This Standard does not apply to: (1) accessory equipment used to measure pressure and temperature, and\/or density for the accurate determination of mass or base volumes, or those accessories used to automatically compute mass or base volumes; (2) steam metering or two-phase flow measurement; (3) applications involving pulsating flow or fluctuating flows where adverse effects on meter accuracy can be anticipated.<\/p>\n
