Abstract
A plate-liquid-plate (PLP) acoustic resonator is used to measure the acoust ic velocity of liquids. An analytical model of the electrical input impedan ce of tile resonator is proposed. Theoretical results are compared with exp erimental measurements using reference liquids. Accuracy of the sound veloc ity calculation is found to be better than 1%, Finally, factors limiting th e achievable accuracy are discussed.
