AMR is the technology of automatically collecting consumption and status data from water/heat/gas/electricity meter and transferring that data to a central database for billing, troubleshooting, and analyzing.

The basic process flow

1) Upper Communication:

Communication method indicated below can be selected between concentrator and management center.

(a) GPRS Communication Mode

(b)Telephone Line Communication Mode

(c) RS232 Communication Mode

(d) Ethernet Communication Mode

2) Middle Communication

Middle layer communication means the communication between the concentrator and collector. This communication is by wireless RF way, no need of communication line. The wireless communication distance between the concentrator and collector can be about 3km at open environment.

Each piece of concentrator can manage 255 pieces of collector maximally.

3) Bottom Communication
Bottom layer communication means communication between the collector and water meter.

Wireless network signal has the positive of wide signal propagation, wide coverage area ability, fast construction. One piece of collector can connect with 128 pieces of meter maximally.
