  • Patent number: 4428241
    Abstract: An electrode wiring harness for an electromagnetic flowmeter which includes a non-magnetic metal spool having an insulating liner to define a flow conduit for the fluid to be metered, a pair of electrodes being mounted on the spool at diametrically-opposed positions along a transverse axis which is normal to the axis of the electromagnet assembly. The assembly is excited by a pulsatory wave to establish a magnetic field in the conduit that is intercepted by the fluid to induce a signal in the electrodes as a function of flow rate. The harness is constituted by a printed circuit board connected to the electrodes and disposed in a plane parallel to the electrode axis. The board has a conductive pattern thereon providing wiring from the electrodes to an external converter, the pattern including a loop coaxial with the electromagnet axis, whereby voltages induced therein by the magnetic field are balanced out.
