摘要：
A fluid properties measurement device, including a magnetically excited and sensed resonator and a resonator electromagnetic excitation assembly, including an excitation coil driven by an electrical network, electrically connected to the excitation coil. The excitation coil is positioned so that a varying magnetic field produced by the excitation coil will drive the resonator in a pattern of resonating movement that has predetermined characteristics. Also, an electromagnetic sensing assembly, including a gradiometric sense coil is positioned so that an electromagnetic field originating due to movement of the resonator in a pattern having the predetermined characteristics, will create a time-varying gradient across the sense coil. Finally, a signal sensing electrical network is electrically connected to the sense coil.
