Abstract

An equivalent circuit-genetic algorithm based modelling and optimal design approach was proposed to solve the problem of modeling and multi-objective optimal design for ultrasonic liquid level transducers. The equivalent circuit for an ultrasonic liquid level transducer was established by applying the electro-mechanical-acoustic analogy method

and the frequency response function and the output response function of the transducer were derived. In the multi-objective optimal design for the ultrasonic liquid level transducer

the dimensions of piezoelectric ceramics

the protection film thickness

and the gap between the transmitting probe and the receiving probe were chosen as the design variables; the peak-to-peak and the eigenvalue of output voltage were defined as the objective functions; two optimization tools

MATLAB and GA

were employed. The simulation results are in reasonable good agreement with the experimental data and the transducer performance increases significantly. It seems that the equivalent circuit approach can provide a useful tool for modeling ultrasonic liquid level transducers.
