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 ,
  • liquid : water, high temperature water, oil, food liquid, chemical liquid,
  • steam: saturated steam, overheated steam,

Features:

  • No moving parts, wear resistance, structure is simple and fastness
  • The allowed working temperature is wide from -40℃ to +350℃
  • Wide range, High accuracy
  • Meter body adopts stainless steel material, corrosion-proof
  • Pulse signal output, two-wire system 4-20mA current output, RS-485 output
