I. Introduction

With the continuous advancement and development of social technology, intelligent technologies have permeated various industries, bringing revolutionary changes to traditional management models. In the water industry, meter reading and management has always been a critical task; however, conventional meter-reading methods have numerous shortcomings, such as high labor costs, low meter-reading accuracy, and delayed data acquisition. To address these issues, an intelligent remote monitoring system for smart water meters based on IoT technology has emerged. This paper aims to design and implement an intelligent remote monitoring system for smart water meters. By leveraging IoT technology, the system enables remote monitoring and meter reading of water meters, thereby enhancing the efficiency and accuracy of water meter management. We will combine real-world case studies with technical principles to explore in depth the design and implementation of this intelligent remote monitoring system, highlighting its significant importance and value in the application within the water industry.

II. Problems Existing in Traditional Water Meter Measurement Management

First, the problems inherent in traditional water meter measurement and management primarily revolve around high labor costs, low meter-reading accuracy, and delayed data acquisition. Traditionally, water meter readings are manually recorded, requiring substantial human resources and thus driving up costs. During manual meter reading, human factors often lead to inaccuracies, making data errors or omissions more likely and compromising the accuracy and reliability of water meter measurement and management. Moreover, the conventional meter-reading approach also suffers from delayed data acquisition; data updates take a long time, failing to meet the need for timely monitoring and management of water meter data.

Second, traditional water meter measurement and management still suffers from low levels of informatization and inefficient management. Most conventional water meter systems operate independently, lacking a comprehensive, information-based management platform. Data collection, transmission, and analysis are fragmented and outdated, making it difficult to achieve unified monitoring and management of water meter data. As a result, management personnel find it challenging to promptly grasp users’ water consumption patterns and detect anomalies, thus hindering their ability to respond and make timely adjustments. Consequently, traditional water meter measurement and management exhibits significant shortcomings in terms of both the degree of informatization and management efficiency.

Finally, traditional water meter measurement management still faces challenges such as high costs for daily maintenance and fault handling, as well as low resource utilization. Due to the complex operating environment of water meters—where they are easily affected by external factors and operator behavior—their failure rate tends to be relatively high. Under the conventional water meter management approach, daily maintenance and fault handling require substantial human and material resources, resulting in high costs and low efficiency. Meanwhile, owing to the lack of comprehensive monitoring and analysis of water meter usage patterns, resource utilization remains suboptimal, leading to waste of water resources and increased management costs.

In response to the above-mentioned issues, there is an urgent need to introduce a smart water meter remote monitoring system. By leveraging IoT technology, this system can achieve real-time monitoring and remote diagnostics of water meters, enabling timely detection and resolution of meter malfunctions and reducing both routine maintenance and troubleshooting costs. At the same time, the smart water meter system can also provide comprehensive monitoring and analysis of water meter usage patterns, promoting the rational utilization of water resources, enhancing resource-use efficiency, and lowering management costs.

III. Application of IoT Technology in Remote Monitoring of Smart Water Meters

The application of IoT technology in the remote monitoring of smart water meters represents a significant advancement in modern urban management and water resource management. By integrating advanced sensor technology, wireless communication technology, and big data analytics, smart water meter systems can monitor in real time not only water quality (including water usage characteristics) and water volume, but also the operational status of the meters themselves, thereby effectively identifying and addressing various challenges in water resource management.

By leveraging sensor technology, smart water meters not only monitor real-time water consumption but also detect abnormal conditions such as leaks, backflow, and periods of zero water usage. This capability is crucial for conserving water and reducing water resource waste. For example, the system can identify anomalies where the current month’s water consumption exceeds the previous month’s by more than 30%, which could indicate a leak or unauthorized water use and calls for immediate action. Additionally, the communication module’s low-battery alert promptly notifies management personnel to replace the battery, ensuring uninterrupted data transmission. In terms of wireless communication technologies, the smart water meter system employs NB-IoT (Narrowband Internet of Things) and 4G transmission technologies. These technologies support long-distance, low-power data transmission, enabling the water meters to send real-time data to the central management system even without physical connections. The adoption of these wireless communication technologies significantly enhances the system’s coverage and flexibility, allowing monitoring to be implemented even in remote or hard-to-reach areas.

For both non-resident and residential water meters, the system conducts statistical analysis based on data uploaded daily, including year-on-year and month-on-month comparisons of water consumption. This helps managers understand water-use trends and develop more effective water resource management strategies. Nighttime water-volume monitoring is particularly useful for detecting hidden leaks, as water consumption typically decreases at night, making any unusual flow patterns a strong indicator of leakage. In terms of on-site repairs, the smart meter system can guide maintenance personnel to take targeted actions based on the type of alarm—such as replacing sensors or communication modules. The system also allows users to annotate the actual on-site conditions and upload photos to determine whether repairs are feasible. For example, if construction activities are underway, the water-meter pit is flooded, or access is blocked, such situations can be recorded directly in the system.

IV. Case Analysis

A certain city’s water utility company has implemented a smart metering system to remotely monitor water quality and quantity within its service area. Within just one month, the system automatically detected dozens of water leaks, including one instance where the nighttime water volume monitoring feature successfully identified a leak in the main pipeline of an office building. This leak had been going unnoticed for several days; without the real-time monitoring provided by the smart meters, it could have resulted in the wastage of thousands of liters of water. Thanks to the timely leak alerts sent by the smart metering system, the maintenance team was able to quickly locate and repair the leak, significantly reducing both water loss and repair costs. The application of smart meters has not only improved the efficiency of water resource management and reduced waste but also, through precise data collection and analysis, has enabled a deeper understanding of water consumption patterns and supported the development of future water resource management strategies.
