Trigger Condition:

User Experience:

Meter experienced a processor hardware glitch or meter factory calibration has been defaulted.

Recommend further inspection of alarm data to verify valid meter calibration.

Technical Details:

-USC failure (oscillator fault, system clock failure).

or

-The calibration structure, which is stored in non-volatile INFOMEM, is corrupt and set to defaults.

Clear Condition:

After triggered this alarm is permanently set to active. The alarm can only be cleared via command.

Update:

When flash files are read on bootup or accessed in response to a command.

Trigger Condition:

User Experience:

Possible loss of the most recent metrology/alarm history, or meter calibration has been loaded with defaults.

Only possible with meter reboot.

Recommend further inspection of alarm data to verify valid meter calibration.

Technical Details:

-Calibration structure could not get loaded with the Master Calibration file or Backup Calibration file.

or

-Loaded a file data entry which is not the newest in the given Flash file.

or

-Error opening a Flash file.

Clear Condition:

This is a one-shot type alarm. It is automatically set to inactive after triggered.

Update: Alarm condition is evaluated every ASIC field sample period.

Trigger Condition:

User Experience:

Absence of water in the meter’s flow tube for 5 minutes continuously.

Technical Details:

Metrology measured impedance exceeds threshold for 5 minutes continuously.

Clear Condition:

Alarm is set to inactive when conditions return to normal.

Update: Alarm condition is evaluated every ASIC field sample period.

Trigger Condition:

User Experience:

An external magnetic field applied to the flow tube disrupts normal flow measurement. Typically indicates an attempt at tampering to stop proper metering.

Technical Details:

If the change in magnetic field per microsecond of field drive is out of range, the alarm will be triggered.

Condition must present for 15 minutes continuously.

Clear Condition:

Alarm is set to inactive when conditions return to normal.

Update: Alarm condition is evaluated hourly.

Trigger Condition:

User Experience:

The meter has been operating for 20.5 years, and the battery is nearing exhaustion.

Technical Details:

After 20.5 years have elapsed since meter’s stored time of manufacture.

Clear Condition:

Alarm is set to inactive when the “End-of-Life" alarm becomes active.

Update: Alarm condition is evaluated hourly.

Trigger Condition:

User Experience:

The meter has been operating for 21 years, the battery exhaustion is imminent.

Technical Details:

After 21 years have elapsed since meter’s stored time of manufacture.

Clear Condition:

Once conditions are met this alarm is permanently set to active.

Indicates a hardware communications error occurred between the metrology processor and the ASIC.

.

Trigger Condition:

User Experience:

The meter’s processor experienced a hardware related communication glitch with the metrology ASIC.

Technical Details:

Hardware or communication failure during ASIC initialization or run-time sampling.

Note: A communication hard lockup of the ASIC chip or SPI bus typically results in a processor reboot in an attempt to recover.

Clear Condition:

Alarm is set to inactive when conditions return to normal.

Trigger Condition:

User Experience:

The meter rebooted. Typically seen after a firmware upgrade.

Technical Details:

Processor reboot due to hardware/firmware issue or firmware upgrade completed.

Clear Condition:

This is a one-shot type alarm. It is automatically set to inactive after triggered.

Voltage between the two electrodes is too large to measure water flow.

Update: Alarm condition is evaluated every ASIC field sample period.

Trigger Condition:

User Experience:

Electrode voltage readings are too high for flow sensor to accurately calculate the flow measurements.

Technical Details:

Conditions are evaluated when meter has been out of Empty Pipe state for 2.5 days (default), and the condition is present for 15 min. continuously.

• -Absolute value of the electrode delta (differential voltage between the electrodes) > 180mV.

or

-The absolute value of the high-resolution ASIC ADC > 220000 counts

Clear Condition:

Alarm is set to inactive when conditions return to normal.

Update: Alarm condition is evaluated every ASIC field sample period.

Trigger Condition:

User Experience:

Flow sensor cannot regulate the magnetic field to the minimum strength required to accurately calculate flow measurements.

Technical Details:

Alarm is set when the measured magnetic field is lower than a third of its normal value (the target value at ‘Normal Field’ setting) for 2 minutes continuously.

Note:

The field drive time will increase during a Low Field condition which may trigger Magnetic Tamper alarm.

Clear Condition:

Alarm is set to inactive when conditions return to normal.

Early detection of high power consumption.

Indication that the meter has been operating more frequently than expected which will affect battery life and potentially the warranty on the meter. The most likely cause is an increase in communications with the meter (for example, repeated meter readings, overactive alarms, or firmware download).

Update: Alarm condition is evaluated every 15 min.

Trigger Condition:

User Experience:

Unusually high meter power consumption detected which could lead to reduced battery life. Commonly caused by meter radio communication such as meter readings or firmware download.

Technical Details:

Estimated power consumption over the past 15 minutes is more than 4 times higher than the target average power consumption.

Clear Condition:

Alarm is set to inactive when conditions return to normal.

Low Primary Battery

(Voltage)

Update: Alarm condition is evaluated every 15 min.

Trigger Condition:

User Experience:

Battery power is almost exhausted as determined by the low battery supply voltage.

Technical Details:

After battery voltage drops below 2.5V for 60 minutes.

Clear Condition:

Alarm is set to inactive when conditions return to normal.

Note: When the alarm occurs, the meter will be put into “End-of-Life” operating mode. In this mode the meter will reduce power consumption and may not accurately measure water flow.

Even if the alarm returns to inactive the meter will remain configured in the End-of-Life operating mode.

Update: Alarm condition is evaluated hourly.

Trigger Condition:

User Experience:

Power consumption has been high for an extended period.

Power to the flow sensor will be reduced to compensate until power usage returns to normal. Flow measurement accuracy may be affected while in the reduced power mode.

Technical Details:

When the “Seconds Used” is 8 weeks greater than “Seconds Active”.

Clear Condition:

Alarm is set to inactive when conditions return to normal.

Update: Alarm condition is evaluated every 15 min.

Trigger Condition:

User Experience:

Meter is operating above maximum temperature of +85DegC.

Technical Details:

ASIC temperature > +85 Deg C for 60 min continuously.

Clear Condition:

Alarm is set to inactive when conditions return to normal.

Indicates one or more calibration factors were not set, or that the calibration file has reverted to defaults.

This alarm is typically only set during the meter manufacturing process.

Trigger Condition:

User Experience:

Indicates meter calibration has default values.

Recommend further inspection of alarm data to verify valid meter calibration.

Technical Details:

-After a processor reset if one or more of the meter calibration factors has not been set.

or

-If calibration factors are reset via command.

Clear Condition:

The required calibration factors have been appropriately set via command.

Indicates an issue with the functioning of the iPERL+ metrology.

-High Electrode Voltage Noise.

-Excessive Flow Rate measured.

Update: Alarm condition is evaluated every ASIC field sample period.

Trigger Condition:

User Experience:

External voltage noise introduced to the meter flow tube is interfering with normal flow sensor measurements.

Technical Details:

- High Electrode Voltage Noise for 30 minutes continuously, and not in empty pipe state.

or

-Excessive Flow Rate

detected in metrology where 8 consecutive samples > maximum physically possible flow for the meter.

Clear Condition:
