Nowadays, automatic water annunciator is used extensively.It plays very important role in fire engine department, company security, and our daily life. 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.
