Alarms
An alarm mechanism is implemented on application to detect any unwanted or suspicious behaviour
during the meter lifetime. The bit assignment for alarms register is as follows:
Air temperature below threshold
Air temperature above threshold
Water temperature below threshold
Water temperature above threshold
Fraud is suspected when several attempts to access one of
the input interfaces are detected.
Small water leakage is sometimes present in the water sys-
tem and causes unwanted water waste over time
Hard water leakage is present when one of the water equip-
ments is draining water, if a pipe has serious damage or if a
faucet is left open
Bubbles are present in water which may lead to unreliable
measurements
Pipe is not filled with water
Meter didn’t measure any flow during a detection window
Backflow is an unwanted flow of water in the reverse direc-
tion. The reverse flow happens when the local water system
presents a higher pressure than in its supply network or
when the supply is interrupted or drained down.
Extremely low battery level. The product must be replaced.
Metrological firmware CRC is incorrect
Meter is tampered, dismantled
Overflow is detected when water flow exceeds the maxi-
mum allowed flow
NB: all thresholds in the table above are configurable.
