hot sales Electromagnetic water flow meter

Basic function 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  Model No.  LXSY-15-40  Application  Civ…
