Integrated Type Smart Vortex Flow Meter For Measuring Compressed Air

?

?

Working principle:


Vortex flowmeters measure flow rate by detecting the
frequency at which alternating vortices are shed from a bluff
body inserted into the flow stream. This principle of
measurement is known as Von Karman’s vortex street
principle: alternating vortices form behind an object in a
stream(Show in the picture).When d/D=0.28,released vortices
are stable(D is diameter of the pipe).Vortex shedding
frequency are related to width of the bluff body and flow
velocity
