N2 - A physically constrained ultrasonic waveform design method based on Particle Swarm Optimization (PSO) is proposed for clamp-on flowmeters operating in micro-flow conditions (pipe < DN20, velocity < 0.1 ms). Voltage Amplitude Difference (VAD) measurements suffer from amplitude instability under sinusoidal excitation due to narrow bandwidth and transducer nonlinearity. By embedding the experimentally derived transfer function into a PSO framework, the optimized waveform achieves a broadened 4.1 MHz spectrum, suppresses harmonics, and reduces envelope fluctuation below ± 0.16%. Experiments confirm improved VAD stability and continuity, offering a robust excitation scheme for low-velocity flow measurement.
