Functional Features
1) Moisture protection
The base table and plastic shell base, as well as the plastic shell base and plastic upper shell, are all designed with full sealing, which has improved the level and can reach IP65.
2) Low power consumption
All components are made of low-power products, ensuring the lifespan of the battery.
3) Data collection
It can automatically collect pulse signals from electromechanical sensors using a dual Hall/dual reed sampling method.
4) Data upload method
① Timed upload method——
When the internal clock of the wireless remote water meter reaches the required time for data upload set by the system, the meter actively uploads real-time data and obtains relevant commands.
② Manual upload method——
At any time, users can upload real-time data and obtain relevant commands by pressing the function button in the wireless remote water meter.
5) Online configuration data upload time
Customers can configure the data upload time online through the backend system according to their needs. There are two ways to upload the data: * * method XX day XX hour XX minute, and upload the data at XX hour XX minute with XX days as the cycle. The second method is to upload data on a monthly basis at XX hours and XX minutes on XX days of each month.
6) Remote valve closing
The valve can be remotely closed through the backend service system. When the valve is closed, users cannot open it through the function button. This function can solve user arrears and cooperate with the backend prepayment function.
7) Remote valve opening
Valve opening can be remotely enabled through the backend service system. After receiving the enable valve opening command, the meter will not automatically open the valve. The valve can be opened by manually triggering the function button.
8) Valve protection
When encountering a valve malfunction, the valve fails to close properly, but the instrument can still maintain data sampling
9) Power on and send data
When the system detects that the alkaline battery has changed from non-existent to present and meets the power on requirements, it automatically uploads data and provides sufficient protection against battery shaking or malicious frequent power on and off.
10) Battery monitoring
When the battery voltage is lower than the set "undervoltage value", the LCD panel will display the character "low battery" and automatically send data to the backend service system.
If the battery voltage is lower than the set "valve closing voltage value", a prompt should be given to close the valve. After replacing the battery, restore normal operation and press the function button to open the valve.
11) Remaining amount and unit price return
When the instrument data is uploaded, the backend system automatically calculates the user's remaining amount and returns it to the instrument along with the current unit price. Users can view the relevant information through the LCD panel.
12) LCD constant display
The LCD of the watch is in normal display mode, usually displaying the user's remaining amount or water volume. Through the function buttons, users can view the remaining amount or water volume, tap water unit price, clock year month day, clock hour minute second, and the last 8 digits of the communication meter number.
When the remaining amount or water volume is zero, the system will notify the user in the form of a text message and provide a prompt in the water company's system. At the same time, the valve can be closed in a timely manner or a one-time overdraft amount can be given according to the water company's system settings (the meter can achieve prompt valve closure), bringing convenience to the user's use.
13) Upload data error function
To avoid data channel congestion caused by simultaneous access of a large number of instruments, different peak shifting mechanisms can be set up for handling large amounts of concurrent data.
14) Fault tolerance mechanism for timed data upload
If the data is not successfully uploaded at once during scheduled upload, the instrument will wait for a certain amount of time before attempting to send again.
15) Internal clock network timing
The instrument adopts a hard clock with an accuracy of ± 5ppm internally, and the accumulated clock error throughout the year does not exceed 10 minutes. In addition, every time the instrument logs into the system, it will perform network timing, and the clock of each instrument is accurate and there will be no deviation.
16) Data Protection
Data can be stored for a long time without being affected by external interference, low voltage, power failure, battery replacement, etc.
