Abstract
Many state-of-the-art flowmeters are based on ultrasonic time-of-flight measurements. To enable an easy, fast and low-cost clamp-on mounting with an appropriate signal level, the materials and geometries must be tailored accord-ingly. Within this study, various materials for coupling wedges and matching-layers were evaluated with respect to acoustic impedance and transmission performance using the finite element method (FEM). Additionally, the inci-dence angle between the transducer and the fluid interface was optimized to maximize energy transfer and to minimize reflections. The simulation results were then compared with experimental measurements, showing im-proved signal quality and consistency across different setups. In future work these highly accurate measurements will be used for an AI-based leakage detection.
