Vortex flowmeters have a flow barrier that creates vortexes alternately on both sides of a stop piece. The frequency of vortexes is proportional to the flow rate. From the flow rate, the volumetric flow rate can be calculated, if the pipe diameter is known.
Advantages of Vortex measurement include simplicity, versatility, and affordable price. It can be used in many applications.
For liquids and gases
Vortex flowmeters can be applied for the measurement of low viscosity liquids and gases.
The electronics components are also available separately, which means that the meter is usable at high temperatures. Flanged models and models mounted between flanges are available.
