Troubleshooting (continued)Table 2-1:
Error Recommended action(s)
Power Failure • Meter has had power removed for a period
of time or the meter restarted itself such as
after a firmware upgrade. The Audit log in
the meter indicates the power fail time.
- If this was an unexpected restart of the
meter, verify the integrity of the power
to the meter and make sure that the
voltage level is the in the range of 11-36
VDC at the meter.
- If this was a known power fail or restart
of the meter, just acknowledge this
alarm.
Sound velocity is outside defined limits • The meter's measured average sound veloci-
ty is outside the defined limits.
- Verify that all chords are measuring the
same Speed of Sound within about
0.15%. Look for alarms that indicate
transducer problems and resolve any of
these issues. This could include failing
transducers, debris buildup on transduc-
ers, or incorrectly entered path lengths
in the configuration.
- If the chords agree, adjust the SSMin or
SSMax using the Edit/Compare Config
utility in Daniel MeterLinkTM so the me-
ter's average speed of sound falls within
these limits.
- Collect a Maintenance log using Daniel
MeterLink and contact your Daniel serv-
ice representative.
