It was found that due to the their different acoustic penetration depths inside the liquid the changes of the surface characteristics of the sensor and the characteristics of liquid near the surface can be identified respectively by combined A0 and S0 modes simultaneously. At the same time  the mass sensitivities of both A0 mode and S0 mode of a 2m Lamb wave sensor were demonstrated experimentally. It was proved that S0 mode has higher sensitivity to surface mass changes and the mass sensitivity of the acoustic sensor can be improved further.
