Configurable alerts
The following integrated alerts are displayed on the meter LCD and transmitted over the integrated radio or NFC interface.
Metrology alerts:
- Water leak
- Water burst
- Air in pipe
- Empty pipe
- Reverse flow over configured time or volume
- No flow over configured time or volume

| 20 years | 1 month |
Each logging interval backup's the following data:
1. Cumulative, forward and reverse volume
2. All possible active alerts
3. Max. and min. flow rates incl. timestamp
4. Max. and min. temperatures incl. timestamp
