摘　　要：两种液态介质的界面位置测量是个困难问题.文中结合碱液与柴油界面的测量问题,叙述了利用超声技术测量界面的原理和仪器的电路组成,介绍了温度、介质成分和乳化层对测量的影响与补偿方法.Measuring the interfacing position of two kinds of liquids is a tough task. Through the measurement of the interface between caustic liquid and diesel oil the principle of measuring the liquid interface by using ultrasonic technology and the circuit composition are described. The effects of temperature, media composition and emulsion layer on measurement are presented and compensation methods are given.
