Wholesale Dealers of Low Flow Flow Meter - SUP-LUGB Vortex flowmeter with temperature & pressure compensation – Sinomeasure

• Measuring principle

  Vortex flow meter work on the principle of generated vortex and relation between vortex and flow by theory of Karman and Strouhal, which specialize in measurement of steam, gas and liquid of lower viscosity. As shown in below illustration, medium flows through bluff body and then vortex is generated, vortices are alternately formed on both sides with opposite directions of rotation, Vortices frequency is directly proportional to medium velocity. Through numbers of vortices that is measured by sensor head, medium velocity is calculated, plus flow meter diameter, final volume flow come out.
