Brief Introduction |
IC Card Prepaid Water Meter is developed from dry-type basic water meter, |
composed of microchip module, controlling valves, LED display, IC Card & reader, and accounting management system. |
  The figure of water volume is displayed directly on screen |
  The water using could be controlled as prepaid method |
Features |
Multi jet, dry dial; Brass body, electronic meter; |
Battery life is more than 6 years based on low power consumption design, low battery alarm; |
Accurate measure due to anti-jamming and magnetic features based on non-magnetic sample patents technology; |

Functions |
|
Display |
LCD screen |
Display status of input water volume, surplus water volume, total volume, payment, closed, open, error, low battery, under attack |
Digital show |
maximum total water volume9999.9m3 |
|
Water supply control |
Auto closes the valve when water volume is little, and open when inserting new prepaid card. |
|
Auto control |
Low battery alarm |
Auto closes the valve when battery is low, prompt to change the battery. |
Hardware security |
Auto closes the valve when the pulse line is cut off, and alarm under attack, which must repaired by administrator. |
|
Anti magnetic attack |
Auto closes the valve when strong magnetic close to the meter, need inserting card to reopen the meter. |
|
Power off detection |
Detecting the circuit after power up to check normal or not. |
|
Waterproof |
Reading card as normal even the meter part is in water. |
|
Auto maintenance |
Automatic switch valve for discharge once a month. |
|
Water quota |
You can set a limit to use water. Unable to input water volume more than limit. |
|
Zero-crossing solution |
User information would feedback to the superior software for processing when the valve failure to close in zero-crossing. Extra water volume will be record. |
|
Working features |
Moisture-proof pulse line |
The pulse output is not affected by moisture, data will record as normal. |
Multi-application card |
The first inserting of card in a new water meter will write in Card No. User ID, Water Volume. A card would serve in a total of 4 set of cold water meter, hot water meter, heat meter and pure-water meter at the same time. |
|
Data Recovery |
When the meter is damaged, please insert the read-in card to collect user data and transfer data by inserting to a new meter. |
|
Initialization |
Remove all information in the meter by inserting Initialization card, and set the starting line of water meter. |
|
Control card |
When the meter break down, please insert control card to detect fault or to force the valve open. |
|
Card Reissue |
You can register a new card with original data if lost the user card. |
