Chapter 4. Error Codes and Troubleshooting
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 BHGE
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
BHGE
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 BHGE
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
