Advantages
- Doppler meters may be used where other meters don't work. This might be liquid slurries, aerated liquids or liquids with some small or large amount on suspended solids. The advantages can be summarized to:
- Obstruct less flow
- Can be installed outside the pipes
- The pressure drop is equal to the equivalent length of a straight pipe
- Low flow cut off
- Corrosion resistant
- Relative low power consumption
Disadvantages
- Can’t measure the clean liquid.
- Unsuitable for highly accurate measurement applications.
