Abstract
A magnetic flow meter includes a magnetic flow transducer positioned to sense the flow of water through the flow meter. The magnetic flow transducer includes first and second electrodes positioned on opposite sides of a measuring channel. First and second magnetic pole pieces are positioned on opposite sides of the measuring channel and orthogonal to the first and second electrodes. The magnetic pole piece includes extending tab portions that are located adjacent to the first and second electrodes on opposite sides of the first and second electrodes. The extended tabs formed on each of the first and second magnetic pole pieces reduce the induced voltage within the electrodes to increase the accuracy of the measurement taken by the magnetic flow transducer.
