This Standard
(a) describes the use of vortex flowmeters, including their physical components, principle of operation, installation, performance, influence factors, and calibration in a closed conduit running full for the measurement of volumetric flow rate and volume flow total of single-phase liquids or gases, including vapors such as steam
(b) describes the use of vortex flowmeters in combination with one or more other process measurements for the inferential measurement of mass flow rate, mass flow total, base volumetric flow rate, base volume total, and heat flow metering
(c) is limited to full-bore flowmeters and does not include the special case of insertion-type flowmeters
