초록
In this paper, the ultrasonic sensor for gas flowmeter was simulated, fabricated and measured with assembly step and piezoelectric vibrator layers. The simulated resonant frequency and the measured resonant frequency were similar except sensor 2. The simulated resonant frequency of sensor 3 was 48 kHz and the measured resonant frequency of sensor 3 was 45.2 kHz. From the results, the ultrasonic sensor for flowmeter could be designed and expected without fabrication.
