    Allowable Maximum Error:
    From the minimum flow to the low zone that does not include the demarcation flow: ±5%;
    From the demarcation flow to the high zone including the overload flow: ±2%. 2.8 Communication Distance: City transmission distance: About 2km
    The number of floors crossed: About 15 floors
    Power Supply: The gateway needs an external 220V power supply; All prepaid costs are stored in the meter reading system. Based on the collected data of water consumption, it is determined whether the user owes fees.


    Communication Introduction:
    LoRaWAN is a set of communication protocols and system architectures designed for LoRa long-distance communication networks. When the module is powered on, it automatically sends a join packet. If no reply from the gateway to the network, the join packet will be sent in intervals. After the module receives the network access permission message by the gateway, it pushes a packet of heartbeat data; Since then, it starts timing. Actively push a pack of heartbeat data at intervals of 6 hours. The data upload mechanism can be timed or quantitative or both, and can also be customized on demand.

    Assembly:

    1.The water meter should be installed in a position where there is clean and dry and no direct sunshine or pollution or drowning.
    2.The water meter should be installed horizontally, and the LCD should be upward.
    3.Water flow must go with the same direction as indicated on the body of the water meter.
    4.When assemble, the valve in front of water meter should be closed.
    5.When assemble, the water meter should be covered to prevent from damage.
    6.The water meter should be connected to the couplings first, and not directly to the water pipe. Extra parts include couplings and nuts.


    Installation and Attentions:
    The installation and use of water meters shall comply with the relevant provisions of Chapter 6 of Standard GB/T778.2-2007 and Article 6.3 of JJG162-2009.

    1. The water meter to be purchased should be based on the flow rate often used in the pipeline, and it should be close to the usual flow rate of the water meter.

    2. Before installing the water meter, foreign matter and contamination in the pipe should be removed.

    3. The installation environment should be suitable, anti- freeze, anti-pollution, waterproof, anti-magnetic and prevent mechanical damage. Water meters should be easy to read, install, maintain, and disassemble.

    4. The water meter should be installed horizontally. The arrows on the case should point in the same direction as the water flow in the pipe. The pipes connected to both ends of the water meter should be installed on the same axis to prevent the water meter and accessories from being damaged.

    5. A stop cock or valve can be installed upstream of the water meter
