Abstract

A transducer for the measurement of density, viscosity, flowrate or suchlike of fluids or flowable solids comprises a resonator having two vibratile beam elements (11, 12), one of which is disposed coaxially within the other. The outer element (11) may be a closed tube which forms a chamber around the inner element (12). Drive means (16) and sensing means (17) may be disposed on a base (13) which provides a common root for the beam elements. <IMAGE>
