Description :
A
water flow meter is an instrument capable of measuring the amount of water
passing through a pipe.
An Electromagnetic flow meter is a volumetric meter which does not have any moving parts and is ideal for waste water applications or any dirty liquid which is conductive or water-based. In this flow meter, a magnetic field is generated channelled into the liquid flowing through the pipe. Flow of a conductive liquid through the magnetic field will cause a voltage signal to be sensed by electrodes located on the flow tube walls.
Advantages :
- Minimum obstruction in the flow path yields minimum pressure drop.
- It can measure forward as well as reserve flow with equal accuracy.
- Low maintenance cost because of no moving parts.
- Corrosive or slurry fluid flow.
Disadvantages :
- Requires electrical conductivity of fluid.
Applications :
- Pipelines
- Refineries
