Fujian Aotai Automation Equipment helps Hengshui build a resilient city

At the end of May 2025, Fujian Aotai Automation Equipment Co., Ltd. actively participated in the construction of a resilient city in Hengshui City, and provided strong support for urban flood control and drainage, underground pipe network monitoring and other work with professional equipment and technology.

Aotai's underground road surface water meter is installed on Hengshui city roads with an underground design, which does not affect the city's appearance. With the built-in battery self-powered, it can work continuously for more than 5 years under normal rainfall and water accumulation; the device measures once every 5 minutes, sends a safety report once every 6 hours when there is no water accumulation, and uploads data once every 5 minutes when there is water accumulation. The stainless steel shell reaches the IP68 protection level and is not afraid of harsh environments.

The manhole flowmeter is based on the ultrasonic Doppler principle. The sensor has a built-in water level sensing function, which can calculate the flow rate and water level signal as flow data; it adopts a wellhead construction method, which is easy to install and can accurately measure the flow of the drainage network, providing reliable data for Hengshui's zoning metering, inflow and infiltration analysis, rainwater and sewage mixed connection investigation and other work. Under the working conditions of measuring and uploading data once every 5 minutes, it can last for 3-5 years depending on the battery capacity.

Underground composite water level meters usually use ultrasonic plus static pressure, and radar plus static pressure can also be selected. The two measurement methods complement each other and are common solutions for underground water level telemetry. The device is powered by a built-in battery and transmits data via wireless 4G. Under the condition of measuring and uploading data once every 5 minutes, it can last for 7 years.

In addition, Aotai also has a rich product line for urban waterlogging monitoring. The side-mounted road surface water meter can be flexibly installed on the side of the road to monitor the depth of water accumulation in real time; the electronic water gauge accurately presents water level changes with high-precision sensors; the water accumulation notice screen can visualize water accumulation information in time to guide citizens to travel safely; the underground leakage detector can effectively detect the leakage of underground lines to avoid leakage accidents in water accumulation environments. In the field of underground telemetry, Aotai's equipment can not only monitor water levels and water volumes, but also cover water quality monitoring functions, ensuring the safety and stable operation of urban underground pipe network systems from multiple dimensions.

Resilient cities refer to cities that can resist disasters with their own capabilities, reduce disaster losses, and reasonably allocate resources to recover quickly from disasters. Fujian Aotai Automation Equipment Co., Ltd.'s various monitoring equipment provides strong support for Hengshui City to cope with disasters such as floods and make scientific decisions to optimize the urban drainage system through real-time monitoring and precise analysis of key data such as urban road waterlogging, drainage network flow, and underground water level. It effectively improves the city's adaptability and resilience in the face of environmental changes and emergencies, and helps Hengshui move forward steadily in the process of building a resilient city.
