Abstract

A plate-liquid-plate acoustic resonator is used to measure the acoustic velocity of liquids. An analytical model of the electrical input impedance of the resonator is proposed. Theoretical results are compared with experimental measurements using reference liquids. Accuracy of the sound velocity calculation is found to be better than 1%. Finally, factors limiting the achievable accuracy are discussed.
