Details of
Critical
Fault
Pressure module is
reporting a critical failure of
the pressure sensing
measurement within the
Meter Body, which may be
caused by one of the
following:
• Meter body failure
• Sensor firmware flow
failure
Power cycle the device. If
the problem persists,
replace the Meter Body

Pressure module is
reporting corruption in
the Pressure
Characterization data
Power cycle the device. If
the problem persists,
replace the Meter Body
Differential Pressure,
Meter Body Temperature
and/orvStatic Pressure
input are extremely out of
range such that the value
is suspect.
Verify that all inputs are
within specifications.
Power cycle the device. If
the problem persists,
replace the Meter Body.
Pressure module is
reporting corruption in
the database in the
Random-Access Memory
(RAM)
Power cycle the device. If
the problem persists,
replace the Meter Body
Pressure module is
reporting corruption
of the Non-Volatile Memory
data (NVM)
Power cycle the device and
if fault is cleared ensure to
configure sensor
parameters. If the problem
persists, replace the Meter

Pressure module is
reporting corruption in
sensor firmware
Power cycle the device. If
the problem persists,
replace the Meter Body

Program Flow Failure. This
fault will get set if any of
the critical part of the code
is not executed after
expected duration.
Power cycle the device. If
the problem persists,
replace the Meter Body
The temperature sensor
(Thermocouple or RTD)
has an open input. The
sensor connections may
be disconnected or broken.
Check the temperature
sensor connections for
disconnections or broken
wires. Repair the sensor
connections
