Detailed information
Executive standard: Far pass water meter radical to express executive standard: Use of product of GB/T 778-1996: Use at metric the characteristic of product of water bulk gross that sheds conduit of classics tap water: The design is scientific, the technology is advanced, use telephone network or technology of communication of net of special railway line to realize personal computer to copy a watch, movable condition monitors the circumstance that use water and water to expend automatic settle accounts. Error of the biggest indication, use condition: From the small division that includes the least flow to come not to include dividing line flow inside: ±5% is the biggest allow actuating pressure (MAP) for 1MPa. From include dividing line discharge to come inside the tall division that has included current-carrying capacity: ±2% (cold water expresses) cold water water meter is the biggest allow temperature (MAT) for 55 ℃ from include dividing line discharge to come inside the tall division that has included current-carrying capacity: ±3% (hot water meter) hot water water meter is the biggest allow temperature (MAT) for 90 ℃ network water meter of Yuan Chuanleng, hot water is main technical parameter is metric and characteristic: Cold water water meter: From inside including the least flow to come not to include the small division of dividing line discharge inside the biggest allow an error to be ±5% ; From include dividing line discharge to come inside in the tall division that has included current-carrying capacity the biggest allow an error to be ±2% . Hot water water meter: From inside including the least flow to come not to include the small division of dividing line discharge inside the biggest allow an error to be ±5% ; From include dividing line discharge to come inside in the tall division that has included current-carrying capacity the biggest allow an error to be ±3% . Control damage: ≤0.1 MPa mechanical parameter: Temperature of environment of electric parameter work: - 15°C ~ 55°C. Environmental relative humidity: <90% . Power supply means: Battery of lithium of 3.6V of provide for oneself, need not exterior power source. Signal collects means: Use double pipe striking spring bistable device of post a letter, make data is collected accurate. Data shows pattern: Mechanical accumulative total shows, computer network shows remotely. Time of the least data that put store: ≥10 year. Network communication parameter: The system uses RS485 communication interface, communication distance is 2000 meters. The communication interface that need branch is used between net watch, have interference rejection capacity strong, the characteristic with low power comsumption, its communication distance is 600 meters. Water meter data goes up means: 1, hold machine (OSR unit network) , 2, PC (LAN local area network runs way) , 3, telephone network is deferent (WAN wide area newwork runs way) . Communication rate: 115, 200bps. Network most high capacity: Support 128 repeater, every repeater can be hanged receive 255 nets to express. Single-track network most high capacity is 32640. Static power comsumption: 20μW. Use wire: 2 core of RVV2×0.5mm2 are parallel cable, the resistor of wire is more than 100 meters each 12Ω
