摘要
本文介绍了ＳＪＮ３０５１型超声料位仪的设计要点、基本原理及实际应用情况。 利用“回声定位”原理对仓、槽、桶、罐内的物料位置进行非接触式连续测量，是声呐技术在空气介质中的应用，随着超声学和电子学的迅速发展，超声测位技术正在不断提高。
This paper deals with the design, basic principle of operation, and practiceal application of the model SJN3051 ultrasonic level measuring system. The ultrasonic measurement of material's level in the bin, slot, backet or pot is basically the application of sonar principles working in air. With the rapid development of ultrasonics and electronics, great advances are made in the field of ultrasonic level measuring technology.
