This document describes the use of vortex shedding flow meters for liquids, gases, and steam, including a glossary and a set of engineering equations used for specifying performance, provides technical information to assist the user in selecting, specifying and applying vortex shedding flowmeters, including influence effects, describes typical construction and provides recommendations for inspection, certification, and material traceability, describes availability of diagnostics associated with vortex shedding flowmeters, provides calibration guidance, does not apply to insertion type vortex shedding flowmeters, applies only to closed conduits running full, applies only to fluid flow that is steady or varies only slowly with time, and applies to fluids considered to be single-phase.
