<p>A solid state transducer (310) for a Coriolis flowmeter having a flow tube (15) adapted to vibrate at a predetermined resonance frequency to determine mass flow rate of a fluid passing therethrough. The transducer includes a driver having a strain element, such as an elongated piezoelectric or magnetostrictive element (318) fastened axially along the wall of the tube. The strain element oscillates in the axial direction along the tube wall to selectively generate and sense vibration of the tube. The transducer is utilized as a driver and as a sensor and outputs a signal responsive to the vibration of the tube.</p> |
