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
- Tampering
