中文摘要：

提出了一个将液体的液位变化转化为电位器电阻的变化的实验装置设计方案,进而推导出液体液位与电位器电阻之间的关系式,最后用惠斯通电桥测量电阻变化来测量液体液位。测量数据表明：该测量手段设计简单,成本低廉,相对误差较小。

英文摘要：

Wheatstone bridge can accurately measure the resistance.This paper presents a design plan of experimental devices featuring the change of the liquid level into the change of the potentiometer resistance,and then deduces the relationship between the liquid level and the potentiometer resistance,and finally measures the liquid level for experimental verification by using Wheatstone bridge to measure the resistance change.The measured data show that the means of measurement is a viable method of measuring the liquid level.
