Study of Ultrasonic Near-Field Region in Ultrasonic Liquid-Level Monitoring System

In the method of monitoring the liquid level based on ultrasonic impedance, the near-field effect can seriously affect the validity of the results. In this paper, we explore the factors affecting the length of the ultrasonic near field. Based on that, we propose the optimal length and the minimum le...
