传统锂电池智能水表的致命缺点是当电池电量不足的情况下将无法可靠的关断水阀，造成无法计费、错误计费以及逃水等情况的出现。使用超级电容器的智能水表能够很好的解决这一问题。

　　The fatal disadvantage of traditional lithium battery intelligent water meter is that when the battery power is insufficient, the water valve can not be closed reliably, resulting in unable to charge, wrong charging and water escaping. Intelligent water meter with super capacitor can solve this problem well.

　　超级电容器在智能水表中的应用优势：

　　Application advantages of supercapacitor in water meter:

　　1、将电池从水表中分离出来，从而可以不考虑电池寿命对水表的影响，延长了水表的使用时间。

　　The battery is separated from the water meter, so the influence of battery life on the water meter can be ignored, and the service time of the water meter is prolonged.

　　2、超级电容器的大电流放电特性保障了水阀关断的可靠性，在外接干电池电量不足时，仍能利用存储在超级电容上的能量将水阀关断。

　　The high current discharge characteristics of super capacitor ensure the reliability of water valve shut-off. When the external dry battery is insufficient, the energy stored on the super capacitor can still be used to turn off the water valve.

　　3、以前一味追求的漏电流指标，主要是为了保障电池的使用寿命，改用超级电容器后，漏电流指标变得不重要。如果电池电量不足，用户可以随时更换。这样，不仅使电路设计简化，减少产品的出厂检验工序，还使产品的成本降低。

　　In the past, the leakage current index is mainly to ensure the service life of battery. After using super capacitor, the leakage current index becomes unimportant. If the battery is low, the user can replace it at any time. In this way, not only the circuit design is simplified, but also the product cost is reduced.
