API Vortex Draft

This document describes the design, installation and operation of vortex shedding flowmeters for the measurement of fluid flows, especially hydrocarbon flow measurement. It is being issued initially as a draft standard in order for the industry to obtain more experience with the technology, as well as to determine where this technology may best be applied within the industry. It will have a term of 3 years, at which time it will either be dropped or considered as a standard in MPMS. One particular area where additional experience is needed prior to converting this to a custody transfer standard is in the area of proving. However, this document may provide guidance for non-custody applications where the technology provides benefit.
