Comprehensive Overview of Sanchuan Wired Water Meters
Principles of Wired Communication
Wired meters commonly use the M-Bus (Meter-Bus) protocol over twisted-pair cables. A master device polls slave meters over two-wire connections, which can also power the meters. It supports long-range (hundreds of meters to kilometers), two-way communication, and is standardized under EN 13757 for reliable data transfer, making it ideal for networked connected water meter systems.
Key Advantages of Wired Metering Systems
Wired systems like M-Bus offer high stability and reliability, strong noise immunity, low power use, easy scalable mesh of hundreds of meters, long-distance links, and secure hashed data—all at lower operating costs than wireless.

FAQs of Sanchuan AMR Meters
What does AMR mean in meter reading?
AMR stands for Automated Meter Reading, commonly referred to as AMR automatic meter reading. It's a technology that automatically collects consumption, diagnostic, and status data from water/gas/electric meters via wireless or handheld/mobile receivers—eliminating the need for manual on-site readings while enabling near-real-time billing and analytics.
How to read an AMR meter?
AMR meters are read electronically using one of two methods:
Walk-by: A technician carries a handheld receiver near meters to pick up RF signals.
Drive-by: A receiver mounted on a vehicle automatically collects readings while driving through meter zones.
What is the difference between AMI and AMR meter reading?
AMR: One-way, intermittent data collection requiring walk by/drive by personnel. Offers basic usage readings, limited frequency.
AMI: Two way, fixed network communications; meters automatically transmit frequent interval data (even hourly), and support remote control (e.g., shutoff, firmware updates). More accurate, proactive, and interactive.
