LUGB-type 2 vortex flow sensor measuring the flow of liquid of steam,gas,and low viscosity according to Carmen and Strouhal relevant spiral produce and on the theory of the flow relationship.As shown in picture,in the meter body vertical insert a triangular prism root namely the happening of the body,when eddies of medium throught the table body, in triangular prism behind the alternate produce in opposite directions regualr karman swirl,its spiral separation and the flow of the medium frequency F speed by sensing head is proportional to the V detected the number of spiral,can measure the flow velocity,again according to the table body mouth.
