Centralized Water Metering Solution

The Centralized Water Metering Solution combines wired remote water meters with concentrators to provide an efficient automatic meter reading (AMR) system for high-density water metering applications.

The solution is suitable for:

Residential communities
Apartment buildings
Commercial buildings
Industrial facilities
Municipal water supply systems
Campus water networks

Water consumption data is automatically transmitted to the enterprise water management platform for centralized monitoring and management.

High-Precision Data Collection

The system uses a high-precision mechanical base meter to measure water consumption accurately.

Available electromechanical conversion methods include:

Photoelectric direct reading
Non-magnetic pulse
Other optional electromechanical conversion technologies

These options support different remote meter reading and smart water management applications.

Concentrator Options

Two concentrator types are available according to project size.

Battery-Powered Concentrator

Supports more than 30 water meters

Mains-Powered Concentrator

Supports more than 800 water meters

Both concentrators upload meter data to the enterprise water management platform for centralized management.
