China IC and RF Card for Prepaid Water Meters, Find details about China IC Card, RF Card from IC and RF Card for Prepaid Water Meters
Application |
Measuring the volume of cold potable water passing through the pipeline |
| Work Conditions |
| Water temperature : 0.1°C- 40°C |
| Water pressure : ≤1.0 Mpa |
| 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; |
Item | 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. |
