DESCRIPTION

NB-IoT water meter is a new type of water meter that utilizes advanced technologies such as modern microelectronics, modern sensing, and NB-IoT wireless communication to measure water usage, transmit water usage data, and settle transactions. Compared with traditional water meters, it has more intelligent functions and higher performance advantages.

WORKING PRINCIPLES

NB-IoT water meter transmits the water measurement data to remote servers or management system by built-in NB-IoT modules. NB-IoT is a kind of narrow band internet of things technology, has the characteristics of low power consumption、wide coverage、large connectivity and so on,are suitable for the application which needs long-term transmission of small amounts of data, such as water meter reading.

FEATURE

● Low power consumption: NB-IoT water meter utilizes low power consumption design,the service life of battery can last up to several years,even more than ten years,reducing the trouble and cost of changing the batteries frequently.

● Wide Coverage: The NB-IoT network has strong penetration and coverage, ensuring stable transmission of water meter data even in areas with weak signals.

● High-precision Measurement: Adopt advanced measurement technology and sensors, measure the water consumption of the users precisely with small error.

● Real time monitoring: Management department can monitor the water consumption of the users in real time by remote server,identify the abnormal water usage behaviors in time,such as water leakage,water-theft and so on.

● Intelligent management: Support for tiered water price、prepayment functions,the users can check the water usage information 、recharge payments through mobile APP 、online business halls.

● Easy installation: There’s no need to wire,install easily and conveniently,reducing the difficulties of construction and cost.
