NB IoT remote intelligent water meter

Introduction:

NB IoT remote intelligent water meters use narrowband cellular technology to package and upload user water usage information to the concentrator. Each water meter has multiple SIM cards that can store user water usage information, and the water management department can monitor the online operation of each water meter in real-time. In the future, the Internet of Things will further expand water management, as well as remote control, pre stored water fees, and other fields. Through effective analysis and remote control of end-user water big data, the efficient use of water resources is effectively improved, and technological means are used to promote scientific and water-saving water use.

Technical parameters of NB IoT remote intelligent water meter:

「1」 Internet of Things Private Network Technology: Using a mobile Internet of Things private network dedicated transmission channel and encryption algorithms certified by the State Security Administration, communication is stable and reliable.

「2」 Using a mobile dedicated module, no SIM card required, and in flight number writing.

「3」 Implement tiered water pricing, supporting both prepaid and postpaid management modes, with up to 6 levels of water pricing settings.

「4」 Equipped with remote control function, operate the water meter on/off valve.

「5」 The base part adopts photoelectric direct reading technology for accurate reading.

「6」 Using standard RFID cards, a dedicated encryption card is used for each household, with multiple software and hardware encryption, making it difficult to decipher and preventing illegal modification of internal data.

「7」 High precision acquisition function, with an accuracy of around 0.02mA for collecting analog signals; The accuracy of collecting switch values is around 0.01%.

「8」 The battery life is ≥ 8 years.

NB IoT remote intelligent water meter features advantages:

「1」 Remote networking allows for the collection of table data in any GPRS signal coverage area, without any distance limitations.

「2」 Each table is directly connected to the server without the need for collection devices, ensuring secure and reliable transmission.

「3」 Ultra long life combination battery: The battery capacitor combination power supply guarantees 8 years of use without replacement.

「4」 Meter reading personnel remotely read the readings of the water meter through GPRS, achieving functions such as metering, protection, and valve control.

「5」 Install valves, the system has remote control valve function.

NB IoT remote intelligent water price reference:

「1」 DN15 caliber with valve control: 200 to 300 yuan per piece; DN15 caliber without valve control: 150 to 200 yuan per piece;

「2」 DN20 caliber with valve control: 300 to 400 yuan per piece; DN15 caliber without valve control: 250 to 300 yuan per piece;

「3」 DN25 caliber with valve control: 450 yuan to 500 yuan per piece; DN15 caliber without valve control: 300 to 350 yuan per piece.

NB IoT remote intelligent water meter manufacturing execution standard:

This product complies with the technical requirements of GB/T778-2007 "Measurement of Water Flow in Closed Full Pipelines - Drinking Cold Water and Hot Water Meters" and J/T224-2012 "Electronic Remote Water Meter". The communication protocol follows the protection level IP68 specified in the "130 Communication Protocol Specification" and the "GB4208-2008 Standard".

At present, NB IoT remote smart water meters are widely used, mainly in smart cities, rural areas, schools, hospitals, and hotels where their operating systems can be seen. Due to its low power consumption, low cost, strong link, and high wireless data transmission coverage, this water meter is very suitable for various water environments. In addition, this water meter does not require wiring construction during installation, so many old residential water supply renovation projects that are not suitable for laying cables will also use this water meter.
