IC Card Prepaid Water Meter
Advantages
External battery placement and easy to replace IC card socket is designed to be waterproof, so the entire meter can stand sprinkling. The meter can work normally even when the meter housing is being sprinkled for less than 2 hours3.The pilot valve is immune from scale deposit and water pressure, and is therefore more secure, stable and reliable.

Product Functions
Items | Functions and Technical Requirements | ||
Basic Functions
| Display Functions
| Functional Display | Limited current input, current input, remaining water volume, cumulative water volume, payment, on/off valve, wrong card, battery replacement and attack signal |
Data Display | Maximum cumulative water volume: 9999.9m3. | ||
Control Functions
| Water Consumption Control | Close valve reminder when the remaining water volume reaches alarming water level; open valve with cards and valve will close automatically when water is all used up; user can use card to purchase water, open valve and control water supply. | |
Low voltage | Close valve reminder when battery voltage is lower than the pre-set value; users can open valve with card. The valve will be completely closed if the battery is not replaced within 24 hours. | ||
Self-checking function | When power on, check the circuit automatically to judge if meter is in normal status or not. | ||
Anti-theft and anti-shear | Valve closes automatically and attack signal displayed when the signal-sampling wire is cut. It can only be repaired by administrator not the user. | ||
Moisture-proof Socket | Moisture of socket does not affect meter reading. It will constantly detect if the IC card slot is normal or not. | ||
Self- protection of battery & valve | Meter opens and closes valve automatically once a month. | ||
Input volume limitation | The meter sets the highest water storage volume. When the sum of purchased water volume & the remaining water volume is larger than the pre-set value, no more input is allowed. | ||
Over zero processing | When the valve breaks down, it does not affect normal measurement and over-zero measurement processing. The user card will transmit relevant information to the host or upper computer accordingly. | ||
Pulse sampling moisture-proof | When the sampling circuit board and the sampling line become moist, signal input and output are still normal without data loss and increase in power consumption. | ||
Self-testing function | The meter can perform self-testing to detect engine failure, storage device mistakes, wrong card, wrong write-back, etc. | ||
Routine Cycle Check | The meter will begin cycle check of up to 10 times once in every 5 minutes when the valve is shut down due to attack. It will resume to normal status when the attack stops. | ||
Usage Functions | Data Recycle | When meter is damaged and needs replacement, the transfer card into the broken meter to read and retrieve data. The data will be transferred to the new meter when the data transfer card is ed into the it | |
Initialization | Insert the initiating card to clear all the information inside the meter and set all the parameters. | ||
Inspection card | Use the inspection card to check the system when the meter runs abnormally. | ||
Card replacement | Replacement card is available when user loses the user card. | ||
Incremental Water Rate
| The user card can register freezed water volume, and count the incremental water consumed. |
