Flow meter circuitry applies a current to the magnetic coil and receives the voltage sensed by the pair of electrodes. A magnetic field spreader is positioned proximate the magnetic coil and is arranged to spread the magnetic field emanating from the magnetic coil and direct the magnetic field into the flow tube. An exterior wrapper extends around the assembly and completes a magnetic circuit.
