The Fujian Aotai Utility Tunnel Water Accumulation Monitoring Solution Supports the Safe Operation of Local Integrated Utility Tunnels in Fujian.
2026-02-27
Fujian Aotai Automation Equipment Co., Ltd. has provided remote monitoring equipment for water levels in drainage pits for a comprehensive utility tunnel project in Fujian Province, enabling automatic monitoring of water accumulation in these pits.
Comprehensive monitoring of water accumulation in utility tunnels is crucial for ensuring the safety of pipelines within the tunnels, preventing equipment short circuits and corrosion, avoiding structural leaks, and mitigating the risk of backflow during flood seasons. It is a key component in maintaining the normal operation and maintenance of underground utility tunnels and guaranteeing the stable functioning of urban lifelines.
The device features a vibrant, eye-catching exterior with an integrated design, boasting a compact structure and small footprint—perfect for installation in the confined spaces of utility tunnels. It’s powered by a built-in high-capacity 76 Ah battery, eliminating the need for an external power source and ensuring long-term stable operation. The entire unit is sealed and waterproof, achieving an outstanding IP68 protection rating. Additionally, it incorporates a built-in atmospheric-pressure self-balancing mechanism, significantly enhancing the accuracy and long-term stability of water level measurement.
The system employs a hydrostatic water-level sensor combined with a pair of conductivity sensors for integrated sensing, enabling precise monitoring of both the depth of accumulated water and the water quality status. The equipment is installed in the drainage sumps within the utility tunnel, continuously collecting data on accumulated water levels and uploading it to the control center. This allows for dynamic monitoring of water-level changes, providing reliable data support for the automated interlocking and intelligent scheduling of drainage equipment in the utility tunnel, thereby ensuring the safe and stable operation of the integrated utility tunnel.
