Ig, because as we know when we place an conductor in magnetic field it will induce an voltage...... The same is here applicable, the flow of a conductive liquid is to be measured... and here the conductor is flow of the liquid, and if we use and metal ( conductor) pipe... it will induce error.... ( adds in its emf into the flows V )....
Thanks mam, Can u explain the selection method of flow meter
What is the need of non conducting and non magnetic part in the pipe????
