1. A device for measuring one or more properties of a flowable medium, the device comprising:
a resonant fluid property sensor coupled to a sensor chassis, wherein the resonant fluid property sensor comprises a balanced torsional resonator configured to vibrate symmetrically around a nodal point at a first frequency;
a support structure coupled to the sensor chassis, wherein the support structure is configured to support the sensor chassis when the resonant fluid property sensor is immersed in a flowable medium; and
a vibrator coupled to the sensor chassis, wherein the vibrator is configured to vibrate at a second frequency and transmit vibrations through the chassis to the resonant fluid property sensor.
