1.3.1 Maintenance logs and reports
To monitor the performance health of the meter, and ensure it is operating within
acceptable specifications, routine diagnostics should be performed. Collecting a
maintenance log gives you a snapshot of the current health of the meter and you can
compare the inspection reports from previously saved logs. Use the Logs/Reports menu
and click Maintenance Logs and Reports. MeterLink™ displays the Maintenance Logs and
Reports dialog box. Choose the time duration, log format and collection rate for the
output file and click the Start button. You can open the file immediately after it is
generated or view it at a later time. It is recommended that a Maintenance log be
collected after an upset in the system.
In establishing a baseline to be used for the trending of the meter diagnostics, it is very
helpful if a set of log files are collected immediately after the meter has been installed in
the field. Preferably, collect the log files at several velocities within the operating range of
the meter. This helps establish that the flow profile is relatively constant throughout the
meters operating range (except velocities below 3 ft/sec where the profile may vary).
Maintenance log collection
Figure 1-1: Maintenance log collection parameters
Trend maintenance log collection
Merging the results of two or more Maintenance logs into a single file, allows you to build
a historical database of the meter's performance. Trending the logs indicates changes
8 Emerson.com/Rosemount
Maintenance and Troubleshooting manual Maintenance
00809-0200-3104 April 2022
from the original installation of the meter, or over time. Looking at a single inspection
report, that is either collected monthly or quarterly, can give you an indication of the
meter's health.
Figure 1-2: Trend log collection
This is important since many diagnostics change slowly overtime. Trending the
maintenance logs helps identify these changes and makes problems much more obvious
than merely viewing a single inspection report. The Trending feature is integral to
MeterLink™ which allows all important parameters to be trended. MeterLink supports
trending files in a Microsoft® Excel ® workbook from multiple 3410 Series meter
maintenance logs. Some parameters like gain, signal level,and noise level may show a shift
over time which can be useful in detecting changes in the meter and the installation.
Maintenance logs or Trend files to be trended must all have matching column headings.
This means the logs must be in the same units (i.e. U.S. Customary or Metric), must have
the same pressure type (i.e. gage or absolute), and must have the same time base (1/
second, 1/minute, 1/hour, 1/day). If not, an error message will be displayed stating the
column headings do not match and the file will not be added to the Workbook to trend
list.
Archive log collection
Archive logs may be collected and the options include:
• Daily log - generated every 24 hours on the Contract Hour
• Hourly log - generated every hour at the top of the hour
• Event log - collects the alarm and event log records

The logs may be collected in a single file or you can choose to collect one type of log. Each
of the Meter Archive logs include the Meter Configuration file.
1.3.2 Pipe cleaning maintenance
WARNING
BURST HAZARD
Before pipeline cleaning and maintenance ("pigging operations"), remove straightening
vanes or flow conditioners.
Failure to comply may cause excessive pressure in the meter system, resulting in death,
serious injury or equipment damage.

Straightening vanes or flow profilers must be removed during pipeline cleaning
maintenance operations (“pigging operation”). If the meter run is pigged with a flow
conditioner in line, pressure may build up and cause the pipes and flanges to burst and
severely injure personnel. The excessive pressure may damage the meter or the
10 Emerson.com/Rosemount
Maintenance and Troubleshooting manual Maintenance

transducer ports may collect debris which may impede data acquisition and flow
measurement.
1.3.3 Visual inspection
Periodically inspect the meter and meter run for signs of components loosening or seals
leaking. This includes:
Procedure
1. Fluids leaking from seals. This could be visually noticed for liquids leaking. It may be
audible for gasses leaking. Ice may also form at a point of a gas leak.
2. Movement of components that should be rigid.
3. Excessive noise due to vibration could be sign of a loose component.
Inspection should be more frequent in systems with a large amount of vibration.

Error Recommended action(s)
Chord failure • Chord is hard failed, and meter is unable to obtain measurement
data from a pair of transducers.
— If a chord is failed and no other transducers are failed or are
reporting status alerts, the issue is most likely isolated to this
pair of transducers or its cabling. Check the transducer wiring
for this pair of transducers to make sure connections are secure
and wired correctly.
— Remove the transducer cable from the transducer and measure
the resistance with an Ohm meter.
• For T-11 and T-12 transducers, remove the transducer cable
from the transducer and measure the resistance with an
ohm meter across the two pins on the back of the
transducer holder. If the value is over 2 ohms, replace the
transducers.
• For T-21, T-22, T-32 and T-41 transducers, remove the
transducer cable and transformer assembly and measure
the resistance with an ohm meter. If the value is not 1
Mohm +/- 0.2 Mohm, try cleaning the pins with alcohol and
a small object like a toothpick to see if that lowers the
resistance. If not, replace the transducers. Measure the
resistance across the two pins on the transformer module
that lead to the electronics. If the value is over 2 ohms,
replace the transformer module. Measure the resistance
across the two pins on the transformer module that lead to
the electronics. If the value is over 2 ohms, replace the
transformer module. Measure the resistance across the two
pins on the transformer module that lead to the transducer.
If the value is not between 30 and 40 ohms for the T-21 and
T-41 transformer module, replace the transformer module.
If the value is not between 50 and 75 ohms for the T-22
transformer module, replace the transformer module. If the
value is not between 7 and 12 ohms for the T-32
transformer module, replace the transformer module. If
possible, measure the capacitance of the transducer with an
LCR meter. If the value is not between 450 and 600 pF for
the T-21 and T41 transducer, replace the transducer. If the
value is not between 215 and 350 pF for the T-22
transducer, replace the transducer. If the value is not
between 400 and 550 pF for the T-32 transducer, replace
the transducer.
• For T-200 transducers, remove the transducer cables from
the transducers and measure the resistance with an ohm
meter across the two pins on the back of the transducer
capsules. If the values are over 2 ohms, replace the
transducer capsules. If the values are under 2 ohms, remove
the transducer capsules, clean and reapply the coupling
fluid to the front face of the transducer capsules, and
reinstall the transducer capsules. If this does not correct the
issue, replace the transducer capsules.

Communication issues
due to blocked network
ports
• Blocked network ports on the computer running MeterLink or on a
company LAN can prevent connections to the meter or prevent
certain features from working. These issues may occur over
Ethernet, Modem and Direct serial connections. Reference the list
of network ports used by MeterLink in the Help file and the
symptoms of having blocked ports. Contact your IT department for
assistance in resolving these issues.
• Error condition of a blocked network:
— Cannot connect to a meter
— Cannot collect Archive log files
— Cannot view or stream waveforms in Waveform Viewer or
Signal Analyzer
— Cannot upgrade firmware
— Communications lost over serial or modem connections while
MeterLink is idle on a screen.
• Symptoms of blocked network:
— If a PING is blocked on this network port, serial or modem
connections could be lost after approximately 15 seconds of
inactivity. This issue can be confirmed by checking the
log_meter_log_file in the Temp data folder. The path of the
Temp data folder is shown in the MeterLink About dialog.
— A blocked FTP port will generally not prevent a connection to
the meter, but will prevent log collections and program
downloads. A blocked FTP port could prevent a connection in
the event the meter is running a newer version of firmware for
which MeterLink does not currently have a database
configuration file. If this is a case, a message stating “Error
reading database config file dbconfig<databaseversion>.xml
from the meter.” will be displayed.
— A blocked DB API port will report “Error 10001 opening
database connection to <IP address>”.
— A blocked Streaming port will report an error message “Unable
to open a control socket”. This will occur when opening the
Signal Analyzer window or clicking Read or Stream to File in the

each meter may be left unconfigured as 0.0.0.0).
• A PC may receive its IP address from an external DHCP server; in this
case, one and only one meter must have its DHCP server enabled
(the DHCP server will serve up to 10 IP addresses to PCs attempting
to talk to all meters on the hub).
• Once a meter's IP address is configured, the meter may be
connected to the hub and accessed using that IP address.

Program download failed
during firmware upgrade
• If the meter power fails during a firmware upgrade process,
perform a backup upgrade in an attempt to connect to the meter
and download the program again.
— In MeterLink, go to the File pull-down menu and select Program
Settings.
— Enable the Allow FTP-only connection.
— For Serial Port Connections: for Rosemount 3410 Series Gas
Ultrasonic meters connect to Port A. You may need to adjust
your Meter Directory settings for the connection so that they
match the port default settings. Port A will default to 19200
baud with a Modbus address of 32.
— For Ethernet Connections: If you are connecting to the meter
over an Ethernet port, you should be able to connect with the
same IP address as normal. If this is unsuccessful, the meter may
have defaulted to 192.168.135.100 with a subnet of
255.255.255.0. Make sure your PC has a compatible address
and attempt a connection using this IP address.
— Make sure your cabling and your Meter Directory record are
setup, then attempt to connect to the meter.
— You will receive a message “Error 10001 opening database
connection to …..”. Click OK and you will be prompted to
“Attempt FTP-only connection ….”. Click Yes and if successful,
theMeterLink™ caption displays “…Connected to <meter
name>…”. Go to the Tools pull down menu and select Program
Download to attempt the firmware upgrade again.
— If the firmware upgrade is successful, the meter should start
working as normally as the meter’s configuration is not
normally lost.
— If the configuration is lost, use MeterLink Tools → Edit/
Compare Configuration to write the saved configuration back
to the meter. The saved configuration files are typically stored
in C:\Ultrasonic Data folder.
— Restart the meter to install the firmware. MeterLink prompts
you with a message that it must disconnect from the meter.
Once the firmware upgrade is complete you will be able to
reconnect to the meter with MeterLink.
— When the meter restarts, it takes about two minutes before you
will be able to reconnect depending on the firmware upgrade
being performed. If the database does need to be reinitialized,
it could take up to five minutes.
— After an upgrade, it is recommended to reconnect to the meter
and repeat the Program Download process.
— If all the program components are successfully updated, they
will show to be the same date and version as the Currently
Installed Versions and the Download button will be disabled.

— 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 transducers, or incorrectly
entered path lengths in the configuration.
— If the chords agree, adjust the SSMin or SSMax using the Edit/
Compare Config utility in MeterLink™ so the meter's average
speed of sound falls within these limits.
— Collect a Maintenance log using MeterLink and contact your
