  • Water distribution and drainage systems
  • Bulk water and pipeline monitoring
  • Water conservancy and irrigation projects
  • Remote metering and smart utility platforms

Description

The ZLINK HXW310-F NB/GPRS remote communication module is a low-power, long-life communication device designed for remote data acquisition and monitoring in water supply, wastewater, and water infrastructure networks.

Built with a micro-power design and an integrated lithium battery, the HXW310-F enables long-term, maintenance-free operation in challenging field conditions. Using its RS-485 interface, the module collects data from water meters, flow meters, and pressure transmitters, and securely transmits this data to remote platforms via NB-IoT, GPRS, 3G, or 4G networks.

The module is engineered to operate underground and underwater for extended periods, making it suitable for municipal water networks, drainage systems, bulk supply pipelines, and water conservancy projects. Its robust design ensures reliable communication even in harsh environments where access is limited.

By enabling automatic data collection, remote monitoring, and alarm reporting, the HXW310-F supports utilities and operators in improving network visibility, operational efficiency, and asset management. It plays a critical role in the development of intelligent water utilities and smart water infrastructure across South Africa and the broader African region.

Key Features
