Vortex Flowmeter

A Vortex flowmeter comprising a flow sensor operable to sense pressure variations due to vortex-shedding of a fluid in a passage and to convert the pressure variations to a flow sensor signal, in the form of an electrical signal; and a signal processor operable to receive the flow sensor signal and to generate an output signal corresponding to the pressure variations due to vortex-shedding of the fluid in the passage.

Vortices occur alternately and regularly to the right and left under a given condition downstream of an object (delta shape bluff body) placed in the flow. This vortex is called Karman vortex, enabling you to know the flowrate from the frequency created. A vortex flowmeter is applicable to liquid, gas, and steam. It has no moving parts and features low pressure loss. It is an easy-to-use flowmeter with high durability and repeatability and is widely adopted in various fields including calorie transactions and calorie control.

Features:

  • Compact structure
  • No moving parts, long service time
  • Long time stability
  • Same sensor can measure liquid, gas and steam
  • With acceptable Reynold number, the meter coefficient is free from the influence of the change of temperature, pressure, viscosity and others
