A large aluminum plant operates critical processes such as deep‑well casting, molten aluminum cooling, profile quenching, and recirculating water replenishment. These processes have high water demand and require extremely stable water pressure and levels. For a long time, management faced significant challenges in water control: pressure gauges and level meters deployed across the cooling system, circulating water tanks, and supply pipelines relied on manual rounds for data collection. This approach was not only inefficient and prone to human error, but also unable to provide 24/7 real‑timemonitoring, making it difficult to quickly detect anomalies and take corrective action — affecting both production efficiency and increasing water waste.

To address this, WideIOT deploys IO data acquisition terminals that connect to pressure gauges, level meters, and similar devices. The terminals collect water pressure and level data (4–20 mA analog signals) and transmit it wirelessly via 4G to the DCS system in a remote control room. This enables precise monitoring and control of each pipeline network, improving water management efficiency and utilization while ensuring safe water supply for production, and enhancing digital management capabilities.

Key Features

1. Flexible Analog Input & Protocol Support – Supports 4–20 mA and 0–10 V analog inputs, and is compatible with Modbus RTU/TCP, OPC UA, and other protocols. It can be seamlessly integrated with DCS systems with fast deployment and low cost.

2. 4G Wireless Connectivity – Built‑in 4G module eliminates the need for cabling, enabling real‑time data transmission to a remote DCS system. Ideal for plant retrofit projects without disrupting normal production.

3. High‑Frequency Data Acquisition & Real‑Time Alerts – Supports high‑frequency data collection with real‑time synchronization to DCS screens. Customizable threshold alerts can be delivered via SMS, WeChat, or email for rapid anomaly response.

4. Local Data Buffering – Built‑in local storage automatically caches data during network interruptions and resumes transmission once connectivity is restored, ensuring complete and continuous data integrity.

5. Remote Device Management – Remote configuration and firmware upgrades can be performed through a cloud platform, significantly improving device maintenance efficiency.
