Fujian Aotai Side-Mounted Road Flood Monitor: A Multi-Scenario Adaptable Urban Flood Monitoring Solution

As urban construction upgrades towards intelligence and precision, the demand for water accumulation monitoring is becoming increasingly urgent in projects such as urban lifelines, resilient cities, sponge cities, smart cities, urban flooding monitoring, and intelligent urban drainage. The side-mounted road surface water accumulation meter developed by Fujian Aotai Automation Equipment Co., Ltd. has not only achieved significant results in a low-lying area flooding monitoring project in Hubei Province, but also provides an efficient and feasible method for monitoring road surface water accumulation in the aforementioned urban construction projects.

The core advantage of this equipment lies primarily in its convenient installation: no complex construction is required; it can be directly fixed to roadside surfaces such as curbs, requiring only two M8 expansion bolts for installation, significantly reducing installation labor costs and enabling rapid deployment.

In terms of water level sensing accuracy, the device employs a three-mode composite sensing technology to ensure accurate and reliable monitoring data:

- 6-channel conductivity sensor: Provides range compensation for water level measurements from 0 to 6 cm, accurately covering low-water-level monitoring scenarios;

- Hydrostatic pressure sensor: Measures water level height by sensing water pressure, adapting to medium- and high-water-level monitoring needs;

- Ultrasonic sensor: Calculates the distance to the water surface using the principle of sound wave reflection, further improving monitoring accuracy.

Simultaneously, the entire unit uses a potting process, possessing IP68 protection capabilities, enabling stable operation in complex outdoor environments and effectively resisting water immersion and dust corrosion.

Data transmission and battery life are equally impressive: Measurement data is first transmitted wirelessly to a nearby signal concentrator, then collected uniformly by the concentrator and uploaded to the server in real time via a 4G IoT channel, achieving efficient data flow; the built-in 76 Ah battery provides a battery life of 5-10 years, reducing subsequent maintenance costs. Furthermore, the device is equipped with an atmospheric pressure self-balancing algorithm, covering a typical water level measurement range of 0-3 meters, meeting the monitoring needs of most urban roads.

In terms of protective design, the equipment uses 2mm thick stainless steel plates and is equipped with a 45-degree angled anti-collision contact surface, ensuring both the equipment's own robustness and durability, and effectively resisting external impacts to ensure continuous and stable monitoring.

In mid-to-late November 2025, with the increasing demand for urban flood control, disaster reduction, and intelligent management, Fujian Aotai's side-mounted road surface water level meter, with its comprehensive advantages of "easy installation, accurate sensing, excellent protection, high transmission efficiency, and long battery life," is becoming an important support for solving the problem of monitoring low-lying urban flooding in various urban construction projects, providing strong protection for the safe operation of cities.
