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
Pressure module is
reporting corruption in
the Pressure
Characterization data
Differential Pressure,
Meter Body Temperature
and/orvStatic Pressure
input are extremely out of
range such that the value
is suspect.
Pressure module is
reporting corruption in
the database in the
Random-Access Memory
(RAM)
Pressure module is
reporting corruption
of the Non-Volatile Memory
data (NVM)
Pressure module is
reporting corruption in

Program Flow Failure. This
fault will get set if any of
the critical part of the code
is not executed after
expected duration.
The temperature sensor
(Thermocouple or RTD)
has an open input. The
sensor connections may
be disconnected or broken.
