利用电源电表和两个作为电极的裸导线串联而成的水位仪,是通过电极入水深度与电流值的关系来测水位的。但因我们水库的水质和温度的变化,使得这种水位计所测得的数值误差很大。针对此情况,经过研究,现在采用了对水温及水质变化的自动补偿线路,并以零点法来测读水位,它的简单原理如图①:其中E_1、E_2、R_(p1)、R_(p2)组成了 The use of power meters and two bare wires as electrodes in series is a water level meter that measures the water level through the relationship between the depth of the electrode and the current value. However, due to the change of water quality and temperature in our reservoir, the numerical error of this kind of water level meter is very large. In view of this situation, after research, now uses the automatic compensation of water temperature and water quality changes line, and zero point method to read the water level, its simple principle shown in Figure ①: Where E_1, E_2, R_ (p1), R_ (p2 )formed
