摘要
改进了一种利用磁悬浮和霍耳效应的液体密度计及其标定方法。描述了该密皮计的结构，给出了分段拟合二变量实验曲线的标定方法。这种密度计适用于在太阳池中连续地测量不同深度处盐水的浓度和密度。计算表明，在太阳池中可能出现的温度和盐浓度的范围内，标定结果与实验数据精确相符。
density meter for liquids, based on magnetic levitation and Hall effect, has been improved. Its structure is described and a calibration method by curve fitting in parts is presented. This device is quite suitable for solar pond to measure salinity and density of salt brine. It is proved from calculation that the results of calibration are precisely coincident with experimental data in the possible temperature and salinity ranges of solar pond.
