Collected and Processed data

• Master data 
  • Serial number of the connected meter 
  • Serial number of the communication gateway 
  • Firmware version of the communication gateway 
  • Firmware checksum 
  • Pulse weight (e.g. 0,01 m3/pulse) 
  • RTC (real-time clock) in UTC format 

• Data collection parameters 
  • Integration period (default: 1 hour) 
  • Messaging period (default: 1 day) 

• Consumption alert parameters 
  • Qmin threshold 
  • Qmin duration 
  • Qmax threshold 
  • Qmax duration 
  • Block meter detection duration 
  • Leakage detection duration 

• Consumption register (actual value): pulse count, xxxxx.xxx m3 
• Data log 
  • Consumption register values at the end of integration periods 
  • Consumption register values at the end of messaging periods 
  • Consumption register values at the end of month 

• Operation log

Communication types

• Scheduled PUSH communication (Gateway -> Head-End) - initiated from device side in given periods (parameter): 
  • Data log in ABL file format or DLMS/COSEM (EN 62056) format messages 
  • Push messaging framework makes it easy to implement other protocols 
  • Technical data in hearth-beat messages (signal quality, battery status, etc.) 

• Prompt PUSH communication (Gateway -> Head-End): 
  • Alert messages 
  • Heart-beat message initiated manually from device side with magnet or push button inside the device 

• Pull (Head-End -> Gateway) - as a response to a push message. 
  • Master data settings 
  • Parameter settings 
  • Cross-checked register value 
  • Real-time clock synchronization 
  • Operation log request (for a given period) 
  • Consumption data resend request (for a given period) 

Alerts

• Magnetic sabotage detection on gateway 
• Gateway removed 
• Gateway opened 
• Battery voltage low 
• Block detection 
• Leakage detection 
• Volume above Qmax 
• Volume below Qmin
