A conical resonator using the acoustic near-field technique has been designed and developed. This resonator design is sensitive to the density and viscosity of liquids, as well as to the modification, without discontinuity, of the rheological properties of viscoelastic media. The experimental measurements agree with the results expected from the modelling of the resonator.
