Functional characteristics

A. It takes RF card as an information carrier and has Characteristics of very strong confidentiality and anti- interference.

B. The data adopts the encryption calculating way of DES, and each meter has the only number, in order to correspond one by one.

C. It adopts lithium battery power supplies and can promise to use normally for over eight years.

D. The appropriation dynamoelectric valve promises a dependable switch.

E. The integral whole type designs, beauty and hard, water tightness, attack defend and breakage defend.

F. The LCD shows appearance of the amount of water, date, time, meter number, mode etc.

G. Advanced alarm function: When the customer’s intelligence water has already closed, such as low power, communication abnormality etc. It can provide an alarm hint to the customer with the buzzer, so that the customer handles it as soon as possible, insuring customer to use water normally.

H. Close valve function: the meter will close valve when it reach alarm level and when the prepay amount used out.

I. Low power hint function: When the battery gives or gets an electric shortage, the LCD displays " ", reminding the customer to replace battery.

J. The water meter adopts in volatile memory to store data. The data will not lose while power-fail, the data can keep over a decade.

K. Intelligent self-check function: guarantee working credibility under various interference circumstances.

L. the total amount calculating function: the intelligent meter can record the month and history usage of customer, for the purpose of customer’s search.
