水表厂的电池采用的是CR18505锂猛防水电池它的总容量是3200MAH有效容量是2000MAH,他的使用年限是8-10年,防水电池采用的防渗膜,防水等级很高,不会造成因水压增高而爆炸或者短路!同样电路板也一样,由于密封不够而引起的电路板元器件烧毁等各种情况!而水表厂这类智能水表制作爱普生晶振大厂在生产过程中每一块水表都伴随着苛刻的实验,所以在水表爆炸频繁的地区,用户一定要对自己的安全负责,要求物业或者房地产公司采购商一定要采购大中型企业生产的品牌智能水表!
安全智能水表怎么用才知道自己家水表是否安全?其次为什么不突出智能水表的品牌,改造用的水表是不是3无产品,质监局有没有介入调查,难道农村自来水改造就会应该用质量次的水表吗?同时我也提醒为用户服务的物业及地产采购商们,为了用户安全及水表爆炸的事件不再重演,请你们不要为省几块钱采购质次价高的智能水表,否则等待你们的是良心不安及牢狱之灾!

关于智能水表的选购问题再一次被提出来,本人个人认为,类似水表,电表等家用计量仪表,在团体采购过程中更多的关注的是智能水表的价格,而非质量!认为智能水表不可能有什么质量隐患!其实质量偏低的智能水表还真存在爆炸隐患.一般来说,日本进口晶振智能水表的爆炸隐患主要在以下几个方面：表头,电池,电路板等三个方面,首先说表头,在水表表头这儿由于密封不严造成的电路电流瞬间增大而导致的爆炸,大品牌的水表表头在密封的同时,还做了双保险的干簧管,保证水表在水压瞬间增大的同时,表头不会收到影响,；其次在电池方面由于质量次的智能水表采用的电池防水等级不够,而导致水压增大时,电池短路引起的电池爆炸,
