Electromagnetic flow meter

  1. 1. IN THE NAME OF THE MOST GRACIOUS THE MOST MERCIFUL
  2. 2. Presented By: <ul><li>Rameez Ahmad Mughal </li></ul><ul><li>BEC-01091032 </li></ul>
  3. 3. ElectroMagnetic Flow Meter Topic:
  4. 4. Introduction <ul><li>A  Electromagnetic flow meter  is a volumetric flow meter which does not have any moving parts and is ideal for wastewater applications or any dirty liquid which is conductive  or water based.  </li></ul>
  5. 5. Working Principle <ul><li>The operation of a  Electromagnetic flow meter  or magmeter is based upon Faraday's Law , which states that: </li></ul><ul><li>“ The voltage induced across a conductor as it moves at right angles through the magnetic field is proportional to the velocity of that conductor.” </li></ul>
  6. 6. Faraday’s Formula <ul><li>E  is proportional to  V  x  B  x  D </li></ul><ul><li>where: E  = The voltage generated in a conductor V  = The velocity of the conductor B  = The magnetic field strength D  = The length of the conductor </li></ul><ul><li>(which in this instance is the distance between the electrodes) </li></ul>
  7. 7. <ul><li>ElectroMagnetic flowmeter use Faraday's Law of Electromagnetic Induction to determine the flow of liquid in a pipe. In a magnetic flowmeter, a magnetic field is generated and channeled into the liquid flowing through the pipe. Following Faraday's Law, 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. </li></ul>
  8. 10. Uses… <ul><li>Pipelines... </li></ul><ul><li>Refineries... </li></ul>
  9. 11. Advantages & Disadvantage <ul><li>Advantages: </li></ul><ul><li>Minimum obstruction in the flow path yields minimum pressure drop. </li></ul><ul><li>It can measure forward as well as reverse flow with equal accuracy. </li></ul><ul><li>Low maintenance cost because of no moving parts. </li></ul><ul><li>corrosive or slurry fluid flow. </li></ul><ul><li>Disadvantage: </li></ul><ul><li>Requires electrical conductivity of fluid. </li></ul>
