BROILTECH Vortex Flowmeter bases on Karman vortex street Principal for detection and metering the liquid, gas and steam. It is widely used in Petroleum, chemical, metallurgy, heat supply
industry, etc.

Vortex Theory: :

One triangular prism vortex generator in the flowmeter, regular vortex will be generated at
both the sides of triangular prism, which is called Karman swirl.

Suppose the vortex generation frequency is F, the average flow velocity of medium is V, d is the width of the surface of triangular prism incident flow, Then we get the computation formula:

f=StV/d

St: Strouhal number (Constant)

Application :

Pure liquids and hydrocarbon with low viscosity (< 10 cP)
Water
Chemicals that suitable with S.S. 316 Material

Saturated steam
Superheated steam

Industrial gases

Compressor air measurement

Gas : air, oxygen, nitrogen, coal gas, natural gas, chemical gas ,
