Product Description
vortex flow meter
Working principle
To install a vortex generator(bluff body)in the fluid,which can produces regular vortex at both sides of the vortex generator altematively.Such vortex is called Karman Vortex.Vortex trains are asymmetrically arranged at the downstream of the vortex geberator. Suppose the generating frequency of the vortex is f,the average speed of the incoming flow of the tested medium is V,the head-on width of the vortex generator is d,and the diameter of the flowmeter is D,and base on the principles of Karman Vortex.
