The ECBS001 photoelectric direct reading water meter is designed for centralized water metering and remote utility monitoring applications in residential buildings, commercial facilities, and building management systems. Supporting RS485 and M-BUS communication interfaces, the meter enables stable and accurate remote meter reading integration for local deployment utility management systems.
Adopts photoelectric encoded direct-reading technology for accurate and stable meter data acquisition.
Supports RS485 and M-BUS communication interfaces for centralized meter reading systems.
Dry dial structure maintains long-term readability and operational reliability.
Non-contact sensing technology does not affect the metering mechanism or measurement accuracy.
Power is consumed only during communication and data reading operations.
Supports CJ/T188-2004, DL/T645-1997, and Modbus communication protocols.
Can be integrated into centralized utility metering and building monitoring systems.
Optional valve control function supports remote water supply control.
