10、his Standard has been prepared by ASME/MFCC/SC16-Vortex Shedding Flowmeters.It is one of a series of standards covering a variety of devices that measure the.flowof fluids in closed conduits.The vortex shedding principle has become an accepted basis for fluid flow measurement.Meters based on this pr
11、inciple are available for measuring the flow of fluids ranging fromcryogenic liquids to steam and high-pressure gases.Vortex shedding flowmeters are alsoreferred to as vortex meters.Their designs are proprietary and,therefore,their design detailsand associated uncertainty bands cannot be covered in
12、this document.However,these deviceshave in common the shedding of alternating pairs of vortices from some obstruction in themeter.The natural laws of physics relate the shedding frequency,f,to the volumetricflowrate,q.of the fluid in the conduit.The vortex pairs can be counted over a givenperiod of
13、time to obtain total flow.This Standard contains the relevant terminology,test procedures,list of specifications,application notes,and equations with which to determine the expected performance character-istics.This Standard was approved by the American National Standards Institute on February20、199
