Magnetic flowmeter assembly having independent coil drive and control system

A magnetic flow meter assembly having a tubular body that has two opposing ends that define a fluid flow path therebetween for a conductive fluid. The magnetic flow meter assembly further includes a pair of coil assemblies which are configured to pass current as received from voltage regulators via a first and second coil driver. The coil assemblies can therefore generate a magnetic field wherein a pair of measuring electrodes detect a voltage induced by the conductive fluid passing through said magnetic field. Moreover, the coil assemblies are each electrically coupled with at least one sensor that provides feedback to a respective voltage regulator via a proportional-integral-derivative (PID) controller configured to minimize the error between a respective measured current and a target current. The respective voltage regulators can use the received feedback to manipulate the current passing through the corresponding coil assembly to enabling a prescribed magnetic field to be created within the fluid flow for accurate flow measurement.
