The ECBS002 series photoelectric direct-reading remote water meter is designed to measure and record the total volume of potable water flowing through municipal water pipelines. The measured consumption is converted into digital signals and transmitted for remote data collection.
Using handheld data collectors or existing communication networks, the system enables remote meter reading, monitoring, and management, improving the efficiency and accuracy of water usage management.
• Dry-dial structure design.
• Clear and easy-to-read dial with long-term readability.
• Photoelectric encoded passive direct-reading technology.
• Data output via RS485 bus or M-BUS bus.
• Non-contact sensing technology that does not affect meter performance.
• Low-power design, requiring power supply only during data reading.
• Can be integrated with a host management system to realize remote meter reading and monitoring.
• High measurement accuracy, up to R200.
• Optional valve control function, allowing terminals to open or close the valve to control water usage.
