Vortex Flow meters
Method
A vortex flowmeter uses a precision-engineered element called a “shedder bar” placed in the flow path. As the liquid or gas flows around the bar, it creates vortexes or eddies downstream. These vortices alternate sides of the bar—first on one side, then on the other. By monitoring the frequency of these vortex formations, which cause the shedder bar to vibrate, you can accurately measure the flow rate.
Advantages
- Suitable for various liquids and gases
Disadvantages
- Not ideal for fluids with suspended solids or dirty gases
- Requires constant pressure and temperature for accurate gas measurements
- Limited to specific pressure, temperature, and flow rate ranges
