Flowtech Measuring Instrument Private Limited

DESCRIPTION:

Flowtech Vortex Flow Meter is based 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 flow meter, regular vortex will be generated at both thesides 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 widthof the surface of triangular prism incident flow, then we get the computation formula:

            f=StV/d
St: Strouhal number (Constant)

2. Applications1. Pure liquids and hydrocarbon with low viscosity (< 10 cP)2. Water Industry3. Chemicals that suitable with S.S. 316 Material4. Saturated steam5. Superheated steam6. Industrial gases7. Compressor air measurement
