4 - D2O FL1 Product Manual
2.1 INTRODUCTION
The D2O will transmit a range of data during its normal operation. In
addition to the regularly transmitted core flow meter data, the D2O will
also periodically transmit system and notification data relating the ongoing
operation and health of the device.
Data is optimised for transmission through the satellite network, and is then
uncompressed and formatted for analysis by the Zepiro servers before being
presented for end use.
The following tables indicate the data that will be transmitted at various times
during the D2O deployment.
DATA
DESCRIPTION
Engineering Units
The currently set engineering unit associated with the readings (L, kL, ML, Gal, kGal, MGal, m³)
Total Flow Volume
A timestamped total flow volume reading (in engineering units) since the D2O’s initial deployment
Data Points
Up to 7 hourly measurements, each representing the average flow rate per hour. Each measurement is
individually timestamped. The number of measurements included in an individual message will vary within a
24hr period based on synchronisation time settings
Device Integrity Info
Basic information to indicate that the system is performing as intended without alert, tamper or fault
2.2 FLOW METER DATA
This data includes the readings and parameters associated with the flow
meter input, as well as indicates the data integrity. This data is typically
transmitted 4 times a day.
DATA
DESCRIPTION
Battery Information
Includes the current battery voltage and remaining charge level as a percentage
Module Temperature
The temperature of the PCB board within the D2O enclosure in Degrees Centigrade
Current GPS Coordinates The Global Positioning System (GPS) Latitude and Longitude coordinates in 0.001 resolution
RSSI
The Receiver’s background noise level or RSSI (Received Signal Strength Indicator) in dBm
Queue
The remaining storage space in the transmission queue in bytes (0 - 320 bytes)
Sample Counter
The total number of samples taken since the D2O’s initial deployment
2.3 SYSTEM DATA
System data includes diagnostic information about the D2O and is key to
understanding how the unit is performing. This data is continually updated
and is usually transmitted twice a week.
