摘　　要：常用的液位测量传感器存在着易受介质特性影响、动态性能差等问题。根据离子液体的导电理论,提出了一种全新实时测量的动态液面变化的方法,经过在不同的溶液和温度条件下反复实验,证明该方法完全排除了溶液的本性及离子浓度和温度等因素对测量的影响。此方法已成功应用于波高的测量,并且可以推广用于对任何非腐蚀性液体的液面高度的动静态测量。Common liquid level sensors are easily influenced by the liquid characteristics, and have poor dynamic perform- ances. According to the conductive theory of ionic liquid, this paper presented a new measurement method of real-time dynamic liquid level. Through repeated experiments in different solutions and temperatures, it entirely excluded the influence to measure- ment caused by solution nature, ion concentration and temperature. This method was used for measuring the wave height success- fully. It can also be applied to the dynamic or static measurement for any non-corrosive liquid.
