Buy Water Flow Meter Pulse Output Factory – SUP-LUGB Vortex flowmeter wafer installation – Sinomeasure

• Measuring principle

  A fluid flowing with a certain velocity and passing a fixed obstruction generates vortices. The generation of vortices is known as Karman’s Vortices.The frequency of vortex shedding is a direct linear function of fluid velocity and frequency depends upon the shape and face width of bluff body. Since the width of obstruction and inner diameter of the pipe will be more or less constant, the frequency is given by the expression:
  f=(St*V)/c*D
