METER ALARMS
E-Series Ultrasonic meter alarms appear on the display as icons that illuminate when the condition occurs Alarms are
displayed for the number of days listed in the table below Alarms also appear as 3-character codes on the alarm and
operating mode screen See
"Alarm and Operating Mode Screen" on page 11
Alarms are sent as part of the encoder message to AMR/AMI systems that are capable of receiving an extended message, such
as ORION Cellular, Fixed Network (SE) and Migratable (ME) endpoints The details can also be read through an IR interface
OTE:
N
Meters are delivered in storage mode so that an alarm is not triggered In storage mode, the meter LCD displays an
empty pipe icon, but no error code is sent to the endpoint For alarms reported within BEACON, refer to BEACON

Temperature
Temperature outside limits: above 140° F or below
34° F Meter continues to operate but is outside
specified range
Alarm clears after 35 days
unless condition continues
Meter sends consumption and
alarm to the endpoint once per
occurrence
Pressure*
Pressure sensor is damaged, or pressure is outside
specified threshold limits: above
130 psi
or below
20 psi If maximum operating pressure is exceeded,
P
999 PSI
(or
P 99.9 bAr
)
displays until pressure is back
within the specified range If the pressure sensor is
damaged,
P Err PSI
(or
P Err bAr
) will display
Alarm clears after 35 days
unless condition continues
Empty Pipe
Empty or partially filled pipe Last known good read is
displayed
If the meter is active and detects an empty pipe,
water temperature displays
ErrF
(or
ErrC
) If meter is
in storage mode and detects an empty pipe, water
temperature displays
– – – F
(or
– – – C
)
Alarm clears when pipe
is filled
Measurement
Error
Interference of ultrasonic signal Meter is not measuring
properly Meter continues to operate unless sensors are
damaged
Alarm clears after 35 days
unless condition continues
Exceeding
Max Flow
Maximum flow rate exceeded No consumption is
accumulated until flow is back within
specified range
Alarm clears after 35 days
unless condition continues
Meter sends consumption and
alarm to the endpoint once per
occurrence
Reverse Flow
Meter detects one (1) gal of reverse water flow, triggers
the reverse flow alarm icon on the display and sends
alarm message to the endpoint
Alarm clears after 35 days
unless condition continues
Meter detects reverse flow and
sends alarm to the endpoint
once per occurrence
No Usage
Flow rate less than the low flow operating rate for
30 days
Alarm clears automatically
once flow occurs
Meter detects no usage and
sends alarm to the endpoint
once per occurrence
Suspected Leak
Flow rate more than the low flow operating rate for 24
hours
Alarm clears automatically
when flow rate drops below
low flow operating rate
Meter detects suspected leak
and sends alarm to the endpoint
once per occurrence
End of Life
Battery nearing end of life
Alarm is activated
after 19 years and does
not clear
Meter sends alarm message
to the endpoint once per
occurrence
Program Alert
n/a
Meter has been programmed in last 35 days
n/a
Meter sends alarm message
to the endpoint once per
occurrence
*Pressure alarms are available with meters equipped with the optional integrated pressure sensor, and connected to ORION Cellular LTE-M, LTE-MS or
LTE endpoints
