scope:

This Standard:

1) 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;

2) provides technical information to assist the user in selecting, specifying and applying vortex shedding flowmeters, including influence effects;

3) describes typical construction and provides recommendations for inspection, certification, and material traceability;

4) describes availability of diagnostics associated with vortex flow meters;

5) provides calibration guidance;

6) does not apply to insertion type flow meters;

7) applies only to closed conduits running full;

8) applies only to fluid flow that is steady or varies only slowly with time;

9) applies to fluids considered to be single-phased.
