Dayu Electronic Split-Type Ultrasonic Level Difference Meter Successfully Applied in Shanghai Inland River Monitoring

In urban water system management, maintaining a proper water level balance between river channels and adjacent landscaped water bodies is of critical importance. Abnormal water levels not only affect the ecological landscape but may also pose safety hazards due to river water backflow. Recently, a water level monitoring project for an urban inland river and a municipal park pond was successfully completed on Anzhi Road, Jiading District, Shanghai. By deploying the split-type ultrasonic level difference meter independently developed by Fuzhou Dayu Electronic Technology Co., Ltd., real-time intelligent monitoring of internal and external water bodies was achieved, providing reliable technical support for refined urban water management.

Project Background and Core Requirements

This project is located on Anzhi Road, Jiading District, Shanghai. The core objective was to simultaneously monitor the water levels of the urban inland river flowing through the area and the landscaped pond within the adjacent municipal park. There is a hydraulic connection between the two water bodies: when the river level rises sharply due to rainfall or other reasons, there is a risk of backflow into the park pond. Traditional manual inspection methods are inefficient, slow to respond, and cannot accurately calculate the level difference. Therefore, the project owner urgently needed a system capable of real-time, remote, and automatic monitoring of both the river and park pond levels, while instantly calculating the difference between them. This would allow park management staff to fully understand the water level situation from the duty room and promptly initiate intervention measures such as gate control when necessary, truly preventing problems before they occur.

Integrated Professional Solution

In response to the on-site conditions and management requirements, the project owner ultimately selected the split-type ultrasonic level difference meter professional solution provided by Fuzhou Dayu Electronic Technology Co., Ltd.

This solution innovatively adopts a split-type design, separating the high-precision ultrasonic sensor from the transmitter display unit. The sensors are carefully installed at key points along the river side near the duty room and at the adjacent park water area. Utilizing physical sealing with potting compound, the protection rating reaches IP68, enabling long-term resistance to outdoor humidity, rain, and other harsh environments, ensuring the core sensing unit operates stably and consistently. The sensors are directly connected to the transmitter (located indoors or in a protective enclosure) via integrated cables, providing a simple wiring layout and high reliability.

During system operation, the front-end sensors continuously and precisely measure the water surface height, blanking distance (empty height), and ambient temperature of the river and pond. All real-time data is transmitted to the transmitter via cables. The transmitter not only visually displays the real-time level at each monitoring point but also automatically calculates and displays the real-time level difference between the river and the park pond through embedded intelligent algorithms. This critical difference data serves as the most direct basis for assessing backflow risk and making decisions on opening or closing gates.

Project Implementation Results and Value

By deploying Dayu Electronic's level difference monitoring system, the project achieved all the intended management objectives:

Remote Real-Time Monitoring: Duty room staff at the park no longer need frequent outdoor inspections; they can clearly monitor the real-time levels of the river and park pond, as well as the difference between them, directly from the transmitter screen indoors.

Advanced Risk Warning: Continuous level difference monitoring provides clear data indications before the internal and external water level difference reaches a warning threshold, allowing sufficient preparation time for implementing control measures.

Digitalized and Intelligent Management: This transforms traditional experience-based water level management into scientific decision-making based on precise data, significantly improving water management efficiency and emergency response speed, effectively safeguarding park facilities and the flood safety of surrounding areas.

The successful implementation of the project on Anzhi Road, Jiading District, Shanghai, fully validates the applicability and reliability of Dayu Electronic's split-type ultrasonic level difference meter in monitoring complex urban hydrological environments. With our professional technology and products, we provided the client with a one-stop solution covering data acquisition, transmission, and intelligent analysis, using technological power to safeguard urban water safety and empower the development of smart water management.
