    3, customers can go to the factory to learn technology.
  • Q About water meter address

    A Use the last 2 digits of the water meter serial number to convert it into a decimal code. The converted code is the table address of the water meter.
    Because our water meter serial number is a hexadecimal code, the software is a decimal code. Therefore, the conversion is required for the software to recognize.
  • Q Ultrasonic RS485 connection

    A According to our guidance document.
  • Q Is the platform free? Can it be prepaid?

    A It is free, and the administrator can pre-charge the amount on the platform to create a user information file for each user.
  • Q What data on the water meter can the platform collect?

    A At present, our platform can collect the accumulated flow, battery voltage and upload time on the water meter, and the ultrasonic LoRa can also collect the instantaneous flow rate.
  • Q Does our platform have a user interface?

    A At present, our account has no user interface, and our customer-customized software can be used as a user interface.
  • Q Lora and Lorawan gateways. What is the role of the gateway? What is the connection with our water meter?
