NB-IoT Smart Water Meter

Hebei Shanghong Meters Technology Co., Ltd. is one of the leading manufacturers and suppliers of nb-iot smart water meter in China. If you're going to wholesale high quality nb-iot smart water meter, welcome to get pricelist and quotation from our factory.

NB-IoT water meter is used to measure the water flow inside the pipeline, through wireless NB-IoT network to upload meter data.

HOW TO USE

NB-IoT Smart Water Meter is used for measuring water flow rate through pipe via wireless NB-IoT network upload water consumption

The whole NB-IoT meter reading system consists of ultrasonic water meter, and monitoring management software. The management center can read and monitor water meter accumulated water consumption, instantaneous water flowrate info by NB-IoT network directly.

NB-IoT water meter can configure 3 days to upload for each month, and in these three days, each day can set 2 time periods to bring device online, and the user can configure time according to the need. During online time, management center can read real-time accumulated water consumption

FUNCTIONS

1. Adopt industrial level NB-IOT module, SIM card

2. Adopt lithium battery: battery lifetime is more than 8 years, and if the power is failure, the data can be saved for 10 years

3. Schedule task to upload and go online : the daily water consumption of current month and last month, accumulated water consumption, balance (water quantity) will be uploaded.

4. Alarm when being attacked, low battery power, low balance, valve failure and owing

5. LCD display, it can display water consumption, signal strength, battery power, valve status, and etc.

Product Overview
NB-loT Internet of Things is characterized by strong links, high coverage, low power consumption,
and low cost. t is also called the "Narrowband Internet of Things".Because of its very low communication power consumption, the NB-loT wireless remote water meter can continue to work for more than six years without 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 and automatically 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 water meters (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.

Technical Features

•Very low activation ratio of the terminal.

5. Product implementation standards
•ISO9001; GB/T778.1.2.3-2007;JJG 162-2009;CJ/T 188-2004.

Product Features
1.Periodic report: report the 24 hours data of the previous day, and the data includes daily freezing information.

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 in the next reporting period, and data within the effecive storage range can be re-reported.

5. Discrete setting: Discrete the reported time points randomly through the program, the minimum estimated length is 10S, and the default is 0 to 8 points to ensure that the communication base station 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
