A It takes RF card as an information carrier and hasCharacteristics 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 byone.
C It adopts lithium battery power supplies and can promiseto use normally for over eight years.
D The appropriation dynamoelectric valve promises adependable switch.
E The integral whole type designs, beauty and hard, watertightness, 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’sintelligence water has already closed, such as low power,communication abnormality etc. It can provide an alarm hint to thecustomer with the buzzer, so that the customer handles it as soonas possible, insuring customer to use water normally.
H Close valve function: the meter will close valve when itreach alarm level and when the prepay amount used out.
I Low power hint function: When the battery gives or getsan electric shortage, the LCD displays " ", reminding the customerto 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 adecade.
K Intelligent self-check function: guarantee workingcredibility under various interference circumstances.
L the total amount calculating function: the intelligentmeter can record the month and history usage of customer, for thepurpose of customer’s search

Relativehumidity:<85%I. Standard caliber: DN15; DN20; DN25 Theinstallation regulationsA. The choice for the caliber ofthe water meter should base on the size of piping flow. B. Theinstallation position should avoid insulation, water flood, frostand pollution, be with convenience of assembles and disassemblesetc. C. The user should keep water meter clean, and be sure tocover the protection cover while it‘s unused. When it’s with dirtor dust, please clean it with soft cloth (or damp cloth thatwringed out). D. The water meter must be installedhorizontally and with typeface upward, the piping exit should beabove and over the water meter. E. Direction of arrowhead onthe watch body is homology to water flow direction F. Themiscellaneous articles or objects, such as freestone, sediment andthread...etc. in the new assembled piping should be cleaned beforeassembling water meter, in order to prevent water meter frombreaking down. G. While installing, a valve should beinstalled in front of the water meter, in order to cutoffheadwaters to mantle or dismantle water meter. H. When thewater meter breaks down, please don’t dismantle it and call thetechnical Personnel of the water enterprise to maintain.
