Advantages and Disadvantages of Vortex Flow meters


#1

Advantages of Vortex meters

1 .Wide rangeability (for Reynolds numbers above l0,OOO).
2. An accuracy of 1 percent of rate.
3.A wide range of sizes.
4. Linear output.
5. Availability of pulse and analog outputs.

Limitations of Vortex meters

  1. A limited range of construction materials is available.
  2. Vortex meters are generally not suitable for slurries or O high-viscosity liquids.
  3. Users cannot check calibration
  4. Turbulent flow is required.
  5. Vortex meters have over range limitations.
  6. Strainers may be required.
  7. Vortex meters are affected by pulsating flow.

#2

Advantages:
6. No moving parts and hence wear free.
7. Easy replacement for old mechanical meters.

Disadvantages:
8. If not sized properly, almost useless. Process medium plays a major role in sizing.
9. Downstream space requirement.
