【摘要】 论述了导电式水位检测计的工作原理。在水池的不同深度分别插入电极 ,由于水的导电性 ,这些电极会随着水深的变化 ,分别呈现绝缘或导通状态。电极将检测结果表示为不同的电压信号 ,从而显示水位高低并在水满时报警更多还原

【Abstract】 An operation principle of conductive water level meter is proposed. Since electrodes in different depth in water reservoir have different state of conductivity changing with water level which is represented in voltage signals the water level meter can be realized to show alarm when reservoir is full.更多还原
