Error code Problem Cause Recommended action
E0: No error No error condition
currently exists
This message appears briefly to
indicate that the meter is now
measuring without errors and any
previous errors have now cleared.
No action is required.
E1: Low signal The ultrasonic signal
strength is poor or the
signal exceeds the
programmed limits.
Poor signal strength may be caused
by a defective cable, a flow cell
problem, an empty pipe at the
channel, a defective transducer
or a problem in the electronics
console. A signal that exceeds the
programmed limits is probably
caused by the entry of an improper
value in the error limits option.
Check the value entered into
the signal min error limits option
(see the entering error limits and
understanding error limits sections).
Also, refer to the fluid and pipe
problems and the transducer
problems sections to correct for
any issues.
E2: Soundspeed The measured
soundspeed exceeds
the programmed
limits.
The error may be caused by
incorrect programming, poor flow
conditions, changing fluid properties
that are outside expected values.
It may also occur if signal quality
is poor.
Compare the measured
soundspeed to tabulated nominal
values for the process fluid and
correct any programming errors.
Refer to the fluid and pipe problems
and transducer problems sections
to correct for any issues. In case you
are unable to clear the errors, refer
to the flow Info section to gather
diagnostics data before contacting
Panametrics.
W3: Velocity
range
The measured
velocity exceeds the
programmed limits.
This warning may be caused by
incorrect programming, poor
flow conditions and/or excessive
turbulence.
Make sure the actual flow rate is
within the programmed error limits
(see the entering error limits and
understanding error limits sections).
refer to the fluid and pipe problems
and the transducer problems
sections to correct any issues.
E5: Amplitude The signal amplitude
exceeds the
programmed limits.
This error may occur due to high
signal attenuation or amplification
due to changes in fluid properties,
transducer/buffer/couplant issues.
Make sure the amplitude is within
the programmed error limits
(see the entering error limits and
understanding error limits sections).
Refer to the fluid and pipe problems
and transducer problems sections to
correct any issues. Refer to the flow
info section to gather diagnostics
data before contacting Panametrics.
E6: Cycle
skip (or)
acceleration
A cycle skip is
detected while
processing the signal
for measurement.
This is usually due to poor signal
integrity, possibly because of
bubbles in the pipeline, sound
absorption by very viscous fluids,
or cavitation.
If this error is caused by changes in
flow rate, it will be auto corrected
when the flow rate stabilizes after
initial acceleration. But, if the error
remains, refer to the fluid and pipe
problems section to correct any
issues. Check the threshold peak
percentage, refer to the flow info
section to gather diagnostics data
before contacting Panametrics.
