Product Description

20mm NB IOT 485 Digital Wireless Brass Remote Smart Water Flow Meter with valve control

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.

Product Description

Brief introduction

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
