Table 21: Flow error description and recommended actions
Error Code
Problem
Cause
Recommended Action
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 and/or
couplant issues
Make sure the amplitude is
within the programmed limits.
If the gain is negative and
Amplitude > 32, change the
Transmit Voltage to “Low”. If it is
still negative, enable Attenuator.
Do not enable Attenuator if the
Transmit Voltage is high.
If the gain is greater than 35 dB,
change the Transmit Voltage to
“High” (Refer Programming
Chapter). Refer to “Fluid and
Pipe Problems” and “Transducer
Problems” sections to correct
any issues. Gather required
diagnostics data before
contacting Panametrics
E6: Cycle Skip
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, this error
will be auto corrected when
flow rate stabilizes after initial
acceleration. But, if the error
stays refer to “Fluid and Pipe
Problems” section to correct
any issues. Check Threshold
Peak percentage, and gather
required diagnostics data
before contacting Panametrics
E15: Active Tw
The Active Tw measurement
is invalid
A transducer, cable is
damaged, or a transducer
needs to be re-coupled. This
may also be due to incorrect
programming, or extreme
process temperatures
Refer to “Transducer Problems”
sections to correct any issues.
In case you are unable to clear
the errors, gather required
diagnostics before contacting
Panametrics
E22: Single Channel
Accuracy
One of the measurement
channels is in error
One measurement channel
is in error; accuracy of the
measurement may be
compromised because
the meter might be using a
sister chord substitution
Check individual channel
errors, refer to this table for
recommended actions to
correct channel errors
