NB-IoT ultrasonic water meter is a new type of intelligent water meter that combines NB-IoT technology with ultrasonic measurement principles. The following is a detailed introduction:
Working principle
Ultrasonic measurement principle: The main use of ultrasonic propagation of the time difference method to calculate the flow rate of fluid. In the water flow, the propagation speed of the ultrasonic signal in the upstream direction will be accelerated, and the propagation speed in the counter-current direction will be slowed down. By measuring the time difference of the ultrasonic propagation in these two directions, the speed of the fluid can be calculated, and the flow rate can be obtained.
NB-IoT communication principle: NB-IoT is a mobile communication technology designed for low bandwidth, low power consumption, and wide coverage application scenarios. Through the built-in NB-IoT module, the water meter wirelessly transmits the measured water consumption data to the cloud server or management platform to achieve remote data transmission and monitoring.
Functional characteristics
High precision measurement: The use of ultrasonic measurement technology, can accurately measure the amount of water flowing through the pipeline, is not affected by impurities in the water, chemicals, etc., high measurement accuracy.
Remote data transmission: With the help of NB-IoT network, water consumption data can be regularly sent to the background server to achieve remote meter reading without manual door-to-door reading.
Real-time monitoring and early warning: Support real-time data reporting, managers can find water anomalies in time. When abnormal water consumption or equipment failure is detected, it can automatically alarm.
Low-power operation: The low-power characteristics of NB-IoT technology enable the water meter to work stably for a long time, usually a lithium battery power supply can ensure the use of more than 6 years.
Easy maintenance: no mechanical rotating parts, reduce wear, reduce the probability of failure, extend the service life, low maintenance costs.
Application scenario
Urban water supply system: can be used in urban residential areas, commercial buildings, schools, hospitals and other places of tap water consumption statistics, convenient water supply department for meter reading and billing management.
Industrial water management: In the industrial production process, it can monitor the water consumption in real time, help enterprises optimize the use of water resources, cost accounting and energy saving and emission reduction management.
Agricultural irrigation control: Installed in the field irrigation system, it can monitor irrigation water consumption, assist in achieving fine irrigation management, improve water resource utilization efficiency, and save agricultural water.
Public facilities supervision: Public water records and management applicable to public areas such as parks, squares, municipal roads, etc., contribute to rational allocation and utilization of water resources.
