Bottom layer communication: M-BUS/485 collector and measurement meter transmit data by M-BUS/485 line with 4 channels, and can connect the meter according to any topological structure. Build in backup battery, could works for 48 hours normally, and the data can be saved for 10 years if power is cut off.2. Middle layer 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 wide open area.3. Upper layer communication: Communication methods indicate 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 ModePerformance&Feature:1.Totally sealed design, waterproof.2. Automatically memorize the wheel code position and no need initiation.3. Avoid external strong magnetic attacking, high performance of anti-interference.4. Effectively solve the phenomenon of reversing and hammering.5. Adopt M-BUS/485 communication interface, with long distance transmission.6. No need power supply for daily work.7. With remote valve control function that can stop water supply remotely.
