  • Electromagnetic flowmeter including electrodes and magnetic pole placed in proximity on one side of the outer wall
    Patent number: 7267012
    Abstract: An electromagnetic flowmeter designed to use a smaller excitation device and applicable to measurement on tubular channels of various sectional shapes. The electromagnetic flowmeter includes an excitation device for forming a magnetic field perpendicular to an outer wall of a tubular channel, and a pair of electrodes for measuring an electromotive force generated by the movement of the electroconductive fluid across the magnetic field. The electrodes and two magnetic poles of the excitation device are collectively placed on the outer wall at one side of the tubular channel.

  • Electromagnetic flowmeter
    Publication number: 20070034015
    Abstract: An object of the present invention is to provide an electromagnetic flowmeter designed to use a smaller excitation device and applicable to measurement on tubular channels of various sectional shapes. The electromagnetic flowmeter 10 includes an excitation device 11 for forming a magnetic field perpendicular to an outer wall 11b of a tubular channel 1, and a pair of electrodes 2a and 2b for measuring an electromotive force generated by the movement of the electroconductive fluid across the magnetic field. The electrodes 2a and 2b and two magnetic poles of the excitation device 11 are collectively placed on the outer wall 1b at one side of the tubular channel 1.
