nb smart water meter with the complete software solution
Product Description
Product Overview
NB-loT Internet of Things is characterized by strong links, high coverage, low power consumption,
and low cost. It is also called the "Narrowband Internet of Things". Because of its very low communicationpower consumption, the NB-loT wireless remote water meter can continue to work for more than six yearswithout changing the battery. Using the NB-loT wireless remote water meter can realize the wireless
automatic meter reading function. At the same time every day, the NB-loT module will collect andautomatically transmit the water consumption data of each household to the management platform.Perform statistical analysis and charge for the water consumption of water meters in the managementarea.
The NB-loT system consists of the NB-loT management system platform, base stations, and loT watermeters (NB-loT). The system has a high degree of automation, can monitor the operation and consumption of the meter at any time, and has a wide range of applications.

Product Features
1.Periodic report: report the 24 hours data of the previous day, and the data includes daily freezinginformation.
2.High-frequency periodic reporting: The sending frequency can be set or changed through the platform ,and the minimum reporting period is every hour
3.Intensive data collection:4 hours from the set start time, one point every 5 minutes, a total of 48 points of accumulated flow.
4.Data repackaging: When data reporting is unsuccessful, the data will be automatically re-reported inthe next reporting period, and data within the effective storage range can be re-reported.
5. Discrete setting: Discrete the reported time points randomly through the program, the minimumestimated length is 10S, and the default is 0 to 8 points to ensure that the communication basestation will not be blocked by a large amount of data in a short time.
6.Remote setting of parameters: Through the near-end handheld infrared reading device and
communicating with the management platform, setting IP, port and other parameters
7. Alarm function: When the battery undervoltage is lower than the predetermined value, the platform will automatically alarm to remind the administrator
8. Time proofreading: When the data is reported periodically, the clock will be automatically proofread with the platform to ensure the accuracy of the time

Water meter
1. How long is the battery life?
Using the ER26500 battery with a capacity of up to 9000 mAh and the frequency of reading the meter once a day, the battery life can reach 8 years.
2. Waterproof rating?
At present, this water meter adopts completely encapsulated and sealed technology. It uses silicone to package the circuit board part, and the battery plug and socket are also sealed to achieve IP68 protection.
3. Can your product run underwater?
This product can be soaked in water, but soaking in water will affect the stability of signal transmission, because it will
greatly affect the signal transmission in water
4. If the valve cannot be closed or opened, how to find and deal with it?
If the valve is blocked by sand and gravel flowing into the pipe, the program in the water meter will try to execute the on-off
valve action within 40 seconds.If the valve cannot be switched normally, the water meter will give up the command and return the ault data to the platform.On the platform, you can easily view the relevant information of the water meter.
Pre-sales and after-sales service
1. Pre-sale service
Patient product introduction.
AMR system demonstration.
Project case introduction.
Support sample ordering.
2. After-sales service
Installation instructions, including software part and water meter part;
Support data to the third management system;
Installation supervision, on-site debugging and advertising training;

Communication and service platform
1. What data can the platform collect from the water meter?
Currently, our platform can collect cumulative flow, battery voltage, and upload time on the water meter.
2. How do you know that the water meter is faulty and there is no data to return?
First, we can check the alarm function on the platform to see if the water meter has no data returned, and then check the
installation environment to see if there is any obvious damage, and can actively trigger the water meter to turn on-line mode
