Advantages and disadvantages of different flow meters such as electromagnetic flow meter, air flow meter, turbine meter, Coriolis mass meter, thermal mass meter, current flow meter, vortex flow meter, etc.
Advantages & Disadvantages of Different Flow Meters
Electromagnetic Flow meters
Advantages
The passage of the flow without obstruction and without creating parts
No moving parts
There is no additional pressure drop
Basically, a flow-insensitive view requires only short inputs and outputs
Unaffected by changes in temperature, density, viscosity, concentration and electrical conductivity
Optimal choice of materials for aggressive or abrasive chemical measuring instruments
Ineffective from pollution and sediments
Especially suitable for transporting hydraulic solids
Linear relationship between flow velocity and measured variable
Operates in both directions of flow (forward and reverse)
The range measurement setting can be optimized
Low maintenance, but still easy to maintain
Limitations
For liquids only
Lower conductivity limit 0.05 μm / cm
Gas components cause errors
