The historical data stored in the ultrasonic water meter includes the hourly positive and negative accumulations for the last 7 days, the daily positive and negative accumulations for the last 2 months, and the monthly positive and negative accumulations for the last 32 months. These data are stored on the motherboard by ModBus communication protocol.
There are two ways to read historical data:
1) RS485 communication interface
When reading the historical data, connect the RS485 port of the water meter to the PC and read the contents of the historical data register. 168 registers for hourly accumulations start at 0×9000, 62 registers for daily accumulations start at 0×9400, and 32 registers for monthly accumulations start at 0×9600.
2) Wireless hand reader
Water meter wireless reader can view and save all historical data. Historical data can only be viewed one by one, but cannot be saved. If historical data cannot be viewed when all historical data is saved, you can connect the reader to the PC and export historical data to view it (historical data is saved in Excel file format).
Note:
1. For details, see the manual of ultrasonic water meter and wireless reader.
2. If you don’t order an RS485 output or wireless reader, just plug in RS485 on the water meter mainboard
Module or wireless module, can read the stored historical data.
