In addition, there are few overseas on-line battery testing processes and methods controlled by manufacturers in our country (for example, non-destructive battery performance testing processes and methods are still not available in our country, whether in battery consumption plants or application units). Think again, from design to consumption, how many details of your smart water meters still need to be perfected (not to rush to put imperfect products into the market even with fatal defects)?

信号采样问标题前至少湿式IC卡预付费水表的采样大局部都采用在采样圈（也叫发信圈）内装干簧管的方式，这种方式的最大问题是：采样圈和干簧管容易被压罩在装配时压裂而受损，特别是有些干簧管被隐形压裂（在工厂内测试没有问题，用于现场后才呈现毛病），更是存在很大的隐患。

At least most of the samples of the wet IC card prepaid water meter before the title of signal sampling are installed with a dry reed tube in the sampling ring (also known as the sending ring). The biggest problem of this method is that the sampling ring and the dry reed tube are easily fractured and damaged by the pressure cover during assembly, especially some dry reed tubes are invisibly fractured (measured in the factory). There is no problem in the trial, but there is a great hidden danger when it is used on the spot.

对电路板、电池、执行器等电子器件的防护目前很多厂家为理解决智能水表实践被处在暗淡湿润等环境，都用灌胶的方式将其电路板封装在一个塑料盒内，电池则用“防水电池”，执行器则用少量的胶将其密封在其构造上。外表上，好似处理了智能水表的防护问题，但其实只不过是掩耳盗铃而已，其理由如下：

At present, many manufac
