NB-IOT ultrasonic water meter

NB-IoT ultrasonic water meter is a new type of intelligent water meter that uses narrowband Internet of Things (NB-IoT) technology and ultrasonic measurement principle. The following will be introduced in detail from its working principle, characteristics, functions, application scenarios and other aspects:

NB-IoT communication principle: Through the built-in NB-IoT module, the water meter will be measured water data, equipment status and other information encoded into digital signals, and then use the wireless channel of the NB-IoT network to transmit these signals to the cloud server or water management platform to achieve remote transmission and interaction of data.
Product characteristics
High precision measurement: ultrasonic measurement technology, no moving parts in the measuring tube, not affected by impurities in the water, wear and other factors, low pressure loss, can achieve high precision water measurement, low starting flow rate, wide range ratio, minimal flow can also be accurately measured.
Remote data transmission: With the help of NB-IoT network, water consumption data can be regularly sent to the background server, without manual meter reading, improving meter reading efficiency and data accuracy, and facilitating centralized management and monitoring by the water department.
Low power operation: NB-IoT technology itself has low power characteristics, combined with the optimized design of the water meter, such as the use of low-power chips, sleep and wake up mechanism, so that the water meter can work stably for a long time, and the battery life can reach several years or even more than ten years, reducing the cost and workload of replacing the battery.
Intelligent warning function: When detecting abnormal water consumption, pipeline leakage, battery power shortage, sensor failure and other situations, it can automatically send alarm information to the management platform to remind relevant personnel to deal with it in time to ensure the normal operation of the water supply system.
Easy installation and maintenance: no mechanical rotating parts, reduce wear, extend service life, reduce maintenance costs. In addition, the requirements for pipelines are relatively low during installation, no parameters need to be set, and installation at any Angle.
High protection level: Usually with IP68 protection level, can adapt to a variety of harsh installation environment, such as outdoor exposure, rain, flooding, etc., to ensure the normal operation of the water meter and data accuracy.
Main function
Flow metering function: accurately measure the volume or mass flow of water flowing through the pipeline, and display water consumption, instantaneous flow and other data in real time.
Temperature measurement function: Some water meters are equipped with temperature sensors, which can measure the temperature signal of the water inlet and provide temperature reference for subsequent data analysis and processing.
Valve control function: According to user needs to achieve the pre-payment function and post-payment water bill payment work, by controlling the switch of the valve to manage water, such as unpaid valve, maintenance valve and so on.
Data storage function: can save real-time data and historical data, data will not be lost after power failure, convenient for users and management departments to query and trace the water consumption and water meter running status.
Application scenario
Urban water supply system: It is suitable for the statistics of tap water consumption in urban residential areas, commercial buildings, schools, hospitals and other places, which is convenient for water departments to settle water charges, monitor water use and manage pipe networks.
Industrial water management: In the industrial production process, it can be used to monitor the water consumption of each production link, achieve reasonable distribution and optimal utilization of water resources, reduce production costs, and also help to monitor and manage industrial wastewater discharge.
Agricultural irrigation control: By monitoring the irrigation water consumption of farmland, it helps to achieve fine irrigation management, accurately supply water according to the water demand of crops, improve the utilization efficiency of water resources, and save water resources.
Supervision of public facilities: It is used to record and manage public water use in public areas such as parks, squares and road greening, which helps to rationally arrange water use plans and improve the utilization efficiency of public water resources.
