A new surface acoustic wave(SAW) liquid sensor system is described. SAW devices offer many attractive feature for applications as many sensors. In this paper two surface acoustic waves having shear horizontal(SH mode) and shear vertical(R mode) displacement have been used for measuring the acoustic properties of liquid. SH and R mode SAW delay line were constructed on one 36° YX LiTaO3 substrate. The SH mode SAW was excited on the X direction and the R mode SAW was excited on the direction at 90° to X on the substrate by interdigital transducer (IDT). The measurements of the acoustic properties of liquid were performed for water/glycerol mixtures. The experimental results show that the velocity of the SH and R mode SAW depend to the viscosity and the density of the loaded mixtures, respectively. These results indicate that the dual mode SAW sensor is very suitable for determining the acoustic properties of liquid.
