20 Dbm Emitter Power AMR Water Meter 433 - 470 Mhz 2000m Transmit Distance

AMR water meter by wireless Lora, multi jet water meter with optional valve DN15-DN25

General introduction:

The AMR, automatic metering read, 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.

Work principle

The remote reading multi jet water meter, is with pulse emitter, through automatic meter reading system consists of M-BUS water meter, collector, concentrator and management software.

1. Basic communication device: M-BUS collector and measurement meter transmit data by M-BUS 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. Relay 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.

3. Upper transfer 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 Mode

FUNCTIONS

1. Totally sealed design, waterproof.

2. Automatically memorize the wheel code position and no need initiation.

3. Avoiding external strong magnetic attack, high performance of anti-interference.

4. Effectively solve the phenomenon of reversing and hammering.

5. Adopting M-BUS communication port, which with long distance communication.

6. No need power supply for daily work.

7. With remote valve control function that can stop water supply remotely.
