This kind of water meter can set a dividing point between 2 different levels of used water volumes, and thus have 3 kinds of water charging price. When the monthly used water volume of the user doesn't exceed the demarcation point, normal price is charged; When it exceeds the limit point A, a higher price is collected, and if the monthly used water volume exceeds the limit point B, a much higher price will be charged. Thus used water volume of the users is rationally restricted, so it can effectively[...]

DDSY201F adopted RF IC Card technology and more advanced than DDSY201 and the technique parameters of the two watt-hour meter are the same.
