NB water meter

Introduction:

The NB water meter adopts NB IoT module modulation and demodulation design, perfectly solving the decentralized ultra long distance communication problem of small data volume in complex environments. One of its notable features is its low overall cost, especially the installation cost. Just like wireless prepaid water meters, there is no need for on-site operations such as drilling holes or wiring. Simply install the meter on the pipeline and it can operate. All debugging is completed entirely on the computer terminal, which is easy to promote nationwide and solves the drawbacks of traditional design solutions that cannot simultaneously consider distance, anti-interference, high power consumption, and the need for a central gateway.

1、 NB water meter technical parameters:

[1.1] Adopting China Telecom (CDMA) IoT private network effectively ensures signal strength and coverage.

【 1.2 】 Pre stored for 8 years at the factory, no need to worry about overdue fees or downtime, ensuring reliable data transmission.

【 1.3 】 Large capacity batteries (equipped with SPC super battery capacitors) are guaranteed to last for more than 6 years.

【 1.4 】 The fully sealed process and button free, built-in antenna design ensure that the product has a waterproof rating of IP68.

[1.5] Support multi tiered water pricing function and implement tiered pricing on the meter.

High definition segmented LCD display, real-time display of user data and water meter status.

Up to 18 months of historical data storage.

[1.8] It has valve closing protection functions such as magnetic interference, power failure, and battery undervoltage.

【 1.9 】 It has remote control function and can remotely operate the on/off valve of the water meter.

The platform supports various payment methods such as water companies, banks, collection agencies, WeChat, etc., which are convenient and flexible.

Adopting a B/S architecture management center, the water meter operation status can be monitored anytime and anywhere, improving the work efficiency of the management department.

【 1.12 】 GPS physical positioning and query.

Valve leakage ≤ 2L/h.

2、 NB water meter price reference:

【 2.1 】 Caliber: DN15 Price: 280 yuan -350 yuan

【 2.2 】 Caliber: DN20 Price: 300 yuan -350 yuan

【 2.3 】 Caliber: DN25 Price: 450-600 yuan

3、 Detailed explanation of the functional advantages of NB water meters:

【 3.1 】 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, greatly improving the waterproof/dustproof level and achieving IP6/5;

【 3.2 】 Low power consumption: All components are made of ultra-low power products to ensure the service life of the battery;

[3.3] Data Collection: It can automatically collect pulse signals from electromechanical sensors, using a dual Hall/dual reed sampling method, with patented technical algorithms for anti shake function, and single-sided interference and double-sided interference protection;

[3.4] Data 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;

[3.5] Manual upload method: At any time point, users can upload real-time data and obtain relevant commands by pressing the function button in the wireless remote transmission water meter;

【 3.6 】 Remote valve closing: The valve can be closed remotely through the backend service system. When the valve is closed, the user cannot open it through the function button. This function can solve the problem of user arrears and cooperate with the backend prepayment function;

【 3.7 】 Remote valve opening: The valve can be remotely enabled through the backend service system. After receiving the enable valve opening command, the instrument will not automatically open the valve and must manually trigger the function button to open the valve;

[3.8] Valve protection: When a valve malfunction occurs and the valve fails to close properly, the meter can still maintain data sampling;

【 3.9 】 Power on data transmission: 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;

【 3.10 】 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 once. 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;

【 3.11 】 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 together with the current unit price. The user can view the relevant information through the LCD panel.

NB water meters have high-tech functions such as high accuracy, intelligent fee deduction, water price inquiry, water volume memory, automatic meter reading, balance alarm, and remote information transmission. Its application meets the intelligent water use needs of households, cooperates with the construction of intelligent water networks, and lays the foundation for the implementation of tiered water pricing.
