BROILTECH Vortex Flowmeter bases on Karman vortex streetPrincipal 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

Thermal Intelligent flow switch

introduction:

BROTEK India has all in one, universal, intelligent Thermal flow switch, Its probe with heating element and two

temperature sensor, when no flow both thermal sensor has fix temperature difference, and during flow, flow rate

is directly proportional of temp. difference of thermal sensors,  Temperature difference signal measuring and

control by high precision processor and when its reach at fixed set point switching contact change over,

Thermal flow switch is mass flow rate switch so its measure and control liquid, air and gas with same precision,
