BL118 acts as the core edge device between field instruments and upper-level systems such as SCADA, cloud platforms, and water management software.
It enables:
Real-time data collection from sensors, meters, and PLCs
Local edge computing and alarm processing
Secure data transmission to cloud or control centers
Stable operation in harsh water treatment environments
Typical applications include raw water intake stations, pump stations, filtration systems, wastewater treatment plants, and distributed unmanned sites.
Water treatment projects often involve devices from multiple vendors and use different communication protocols. BL118 offers exceptional protocol compatibility, making system integration simple and efficient.

With BL118, one gateway can replace multiple protocol converters, reducing hardware cost and system complexity.
BL118 comes pre-installed with Node-RED, a powerful visual programming platform widely used in IIoT projects.
Benefits for water treatment systems:
Drag-and-drop flow configuration
No complex programming required
Fast implementation of alarm logic and data processing
Easy protocol conversion and cloud integration
Quick modification and expansion after deployment
This allows system integrators and operators to shorten project delivery time and adapt quickly to changing operational requirements.
Water treatment facilities often face high humidity, electrical interference, and outdoor installation conditions. BL118 is built with an industrial-grade design to ensure long-term stability.
Key reliability features:
Wide operating temperature: -40°C to +85°C
EMC / EMI protection and electrical isolation
Independent hardware watchdog
Industrial aluminum housing
Wide power input: 12–36V DC
BL118 ensures stable, unattended operation, even in remote or challenging environments.
BL118 provides powerful edge computing capabilities, enabling data processing close to the source.
Local data filtering and aggregation
Alarm judgment at the edge
Local data buffering via SD card
Continuous operation during network interruptions
This architecture improves system reliability, data security, and real-time response, which are critical for water treatment operations.
With support for Ethernet, Wi-Fi, and 4G cellular communication, BL118 ensures reliable connectivity in both urban and remote locations.
The built-in BLRAT remote access tool enables engineers to remotely configure, monitor, and maintain devices without on-site visits.
This significantly reduces:
Operation and maintenance costs
Downtime caused by delayed service
Dependency on local personnel
BL118 is not just a gateway—it is a future-ready edge platform for smart water systems.
By combining modular hardware, powerful software, and cloud connectivity, it enables water utilities and integrators to build scalable, intelligent, and data-driven water management solutions.
Industrial-grade reliability for water environments
