Vortex Flow Meter

 

Vortex Flow meter works on the Karman vortex street principle that swirls generated by a bluff body in the pipe.The number of swirls are proportional to the volumetric flow in the pipe. Vortex flow meter widely used for gases, steam and liquid applications. It is ideal for measuring saturated and superheated steam in large facilities to improve steam production efficiency.

 

Principle of Vortex Flow Meter:

 

When the fluid in the pipeline passes the burble generator(triangular prism), burble will generate due to the acceleration of partial flow rate.The burble will rise alternatively in two burble lines, which is called Karman vortex.

 

The releasing frequency of Karman vortex depends on the size of triangle prim and flow rate of fluid, while independent of the medium feature parameter,such as the temperature,pressure,it can be indicated by the following formulas:

 

Application of Vortex Flow Meter:

 

Applications in the chemicals and petrochemicals industries, for example, in power generation and heat-supply systems involve widely differing fluids: saturated steam, superheated steam, compressed air, nitrogen, liquefied gases, flue gases, carbon dioxide, fully demineralized water, solvents, heat-transfer oils, boiler feed water, condensate, etc.
