The magnetic flowmeter assembly includes a pair of electrodes that receive an instantaneous first and second electrode potential (voltage potential), Ue1 and Ue2, so as to determine an instantaneous induced voltage Ue across the fluid.

Abstract: A magnetic flowmeter assembly for measuring the velocity of a conductive fluid in a flow path. The flowmeter assembly includes a coil driver for providing a drive current to a coil assembly, an electrode for measuring an electrical signal created by the conductive fluid flowing through a magnetic field created by the coil assembly, and a micro-processor for controlling the magnetic flowmeter. The micro-processor determines the electrical conductivity of the fluid based on the sensed electrical signal. The micro-processor then modifies the frequency of the coil driver in response to the fluid's electrical conductivity to optimize the sampling rate of the flowmeter. The flowmeter assembly modifies the coil driver frequency by either increasing the drive frequency for highly conductive fluids or decreasing the drive frequency for less conductive fluids.
