title: An analysis of thin-rod flexural acoustic wave gravimetric sensors immersed in liquid.
abstract: A perturbation analysis of acoustic wave propagation properties for a stiff thin rod surrounded by a liquid is presented. A study is made of the velocity sensitivity of the lowest flexural acoustic mode, F(11), along a thin rod due to mass changes in the rod and variations in the surrounding liquid density. It is shown that the presence of the liquid decreases the velocity of the F(11 ) mode and also the mass sensitivity.
