AMR Quarantine Processing
AMR Quarantine Processing lists AMRs that have been quarantined because their reported consumption exceeded the maximum possible throughput of the attached water meter. AMRs reporting negative consumption may also appear here.
Use this report to investigate quarantined AMRs, identify the cause, and process or override the quarantine once resolved.
Access AMR Quarantine Processing from AMR Management in the main menu.

How to investigate a quarantine
The most effective way to diagnose the cause is to click the Error Date value for the AMR. This opens the Water Usage Report (Non-Summarised, Litres Per Minute view) centred on the period around the quarantine event, defaulting to 7 days before and after the highest point on the chart.
Look for a data point that is obviously abnormal compared to surrounding readings. The four most common patterns are described below.
Single abnormal reading
A single spike is clearly visible in the Litres Per Minute chart. In the raw (Non-Summarised) view, the spike may be less obvious — check the data points around the time of the error by hovering over them.
This is typically caused by a data processing issue at the AMR data provider's end — for example, a reading of 180L received 3 minutes after a reading of 0L for the same AMR, producing an artificially high flow rate. Contact the AMR data provider, provide the AMR tag identifier, and ask them to investigate and resend data for the 12 hours before and after the error. Once corrected data is imported, the quarantine will clear automatically.
Single abnormal reading with sudden stop
Similar to the above, but all data from the AMR stops immediately after the high reading. This may indicate a faulty AMR rather than a data provider issue. Raise a field job to inspect the AMR and verify the physical meter reading.
Repeated or constant exceptions
Multiple readings consistently exceed the threshold — typically above 80 litres per minute. This may be caused by an incorrectly configured Rate Per Pulse value on the AMR advice. Contact the AMR data provider to investigate, or visit the property to inspect the meter.
Negative values
The chart shows large negative and positive pulse counts in close proximity. This is usually caused by the AMR data provider reporting timestamps out of sequence — an older, lower value is assigned a later timestamp, which produces a negative delta when Aqualus Water compares consecutive reports.
Contact the AMR data provider to investigate. This type of error often affects multiple AMRs simultaneously. Once the data provider corrects and resupplies the data, all affected AMRs will be corrected automatically — a quarantine override alone will not fix the underlying issue.
Overriding a quarantine
If you've investigated the AMR and confirmed through a field reading that the recorded values are correct and not in error:
Click Process on the AMR Quarantine Processing results.
Confirm the override in the dialog that appears.

The AMR will be removed from the quarantine list.
