The ECBS001 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 water consumption can be converted into digital signals and transmitted for remote data collection.
Through handheld data collectors or existing communication networks, the system enables remote meter reading, monitoring, and management, improving efficiency and accuracy in water usage management.
• Dry-dial structure design.
• Clear and easy-to-read dial that maintains 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 system to realize remote meter reading and management.
• High measurement accuracy, up to R200.
• Optional valve control function, allowing terminal systems to remotely control water supply by opening or closing the valve.
