There are many ways to design its electric circuit, but it has only one function that it alerts when water is full. Work principle, analysis, depend on the concrete electric circuit, such as adjustment of electric circuit, which is very important to analyze the electric circuit work principle, install, adjust and processing electric circuit. We have designed a more perfect electric circuits based on function of automatic water annunciator and analyze systemically the work principle of electric circuit and selection of component parameter. According to work principle and results of adjustment, there are still some problems. We have solved the problems, and changed the component parameter,and made its electric cirtuit accurately.Keywords：Annunciator ; Work principle ; PCB produce flow ; Installment and adjustment-Ⅱ-马培：自动水满报警器1 引言现在生活好了，很多家庭都用上了太阳能热水器，其应用太阳能，清洁无污染，实用价廉，深受喜欢。但市场上出售的大多太阳能热水器水满报警装置太简陋，只设了一条回水管，水从回水管流出来很容易被忽视，易造成水的浪费，而现在却出现了水满报警装置采用了水满自动报警。这种“水满信号”容易被发现，如文中图 1 报警电路所示，它代替回水管的使用，当太阳能水满时，报警器发出柔和的报警音以提醒水满，关闭阀门后，报警音自动停止。它克服了传统回水管易老化，易断，易堵，易冻，费水和水满无声容易遗忘而漫水的缺点等等。因效果好能发声报警并且在市场上价格也较低，所以自动水满报警器广泛应用于太阳能热水器、水箱及储水池等。...
