In this work a novel, highly robust liquid-level sensor system based on the fluid-solid interaction of mechanical ultrasonic solid waves with liquid media is developed. Here, already in the design phase the Finite Element (FE) based simulation of the different coupled field phenomena is taken into account. The focus of the simulation is to characterize propagable transmission modes in the sender / receivers and their efficient excitation using piezoelectric transducers. For the accurate determination of the piezoelectric material parameters a new parameter identification process is conducted. Finally, the possible accuracy of the overall system is quantified in a fully coupled simulation of the complete system.
