Abstract: A magnetic flowmeter includes a field coil extending along the longitudinal axis of a flow conduit for generating an integral magnetic field concentrically located about the coil and perpendicular to the flow. An inner electrode surrounds the coil, and the conduit itself is used as the other electrode, thereby providing a large surface-area electrode for sensing flow induced voltages. High current (over 20 amperes), very short duration (less than 10 millisecond) pulses energize the field coil whose inductance is low enough to permit electrode output voltages to be read within a few milliseconds after the magnetic field current pulse is turned on. The measured output voltage comprises a short-pulse, flow induced component proportional to flow rate, superimposed on a d-c voltage approximately equal to the galvanic potential at the electrodes.
