Advantages
- Low pressure drop
- No moving parts means less wear, no routine maintenance
- Insensitive to density, viscosity, pressure, temperature and flow profile
- Usable for a variety of otherwise difficult to meter fluids
- Accurate (error range of 0.5%)
- Relatively low cost
- Measures independently of temperature, pressure, density, viscosity, and electrical conductivity
- Measures forward and reverse flow
- Can be used with pipes of varying sizes
Disadvantages
- Can only meter liquids
- Liquids must be conductive
- Nearby electromagnetic noise causes interference
- Will not work in partially full pipes, even if electrodes are wetted
- Requires lengths of straight pipe upstream and downstream
- Allowing sludges and greasy fluids to flow too slow causes buildup, which affects measurement
