1.1 Precautions for meter maintenance
This section includes discussion of the maintenance of Rosemount™ 3410 Series Ultrasonic
Meters.
For reference, you may download the MeterLink Quick Start Manual from:
emerson.com/en-us/catalog/measurement-instrumentation/meterlink.
CAUTION
SURFACE TEMPERATURE HAZARD
The meter body and piping may be extremely hot or cold.
Wear appropriate personal protective equipment when coming in contact with the meter.
Failure to comply may result in injury.
CAUTION
TRANSPORTATION HAZARD
When moving the meter, do not insert the forks of a forklift into the bore.
Inserting the forks may cause the meter to become unstable, resulting in injury or damage
to the bore and sealing face.
CAUTION
TRIPPING HAZARD
Clear all obstacles or obstructions from the work area when transporting, installing or
removing the meter.
Failure to clear the work area may cause injury to personnel.

WARNING
CRUSHING HAZARD
Do not remove flange stabilizers.
Attempting to do so could allow the meter to roll, resulting in serious injury or equipment
damage.
A. Flange stabilizers
CAUTION
ESCAPING FLUIDS HAZARD
The purchaser of the meter is responsible for the selection of Rosemount components/
seals and materials compatible with the chemical properties of the measurement fluid.
Failure to select suitable meter components/seals may cause escaping fluids, resulting in
injury or equipment damage.
WARNING
HEARING DAMAGE
Wear proper hearing protection before approaching a metering system that is generating
a large amount of audible noise. Obey all facility safety rules.
Failure to comply could result in temporary or permanent hearing loss.
1.2 Field hydrostatic pressure testing procedures
Rosemount 3410 Series Ultrasonic Gas Flow Meters may be supplied with T-Slot
transducer assemblies which must be removed from the meter before hydrostatic
pressure testing.
T-Slot transducer assemblies are available on 4-inch and larger meters for Rosemount
3410 Series Ultrasonic Gas Flow Meters. The T-Slot assemblies are available on all meter
sizes for the Rosemount JuniorSonic™ Meters (Models 3412 and 3411).
Rosemount 3410 Series Ultrasonic Gas Flow Meters may instead be supplied with T-200
transducers. With full-metal structure, field hydrostatic pressure test can be done with
T-200 transducer in place.

CAUTION
LEAKAGE OR PRESSURE CONTAINING PARTS FAILURE
Use precautions to eliminate hazards to personnel in the event of leakage or failure of the
gas ultrasonic meter pressure containing parts or failure of the test equipment and to
prevent over-pressurization during the test procedure.
Failure to comply may result in injury to personnel or cause damage to the equipment.
1.2.1 T-Slot transducer assembly and mount
Procedure
1. Slowly vent all line pressure on the 3410 Series Gas Ultrasonic Meter to atmosphere.
2. Disconnect transducer cable from the transducer holder.
3. Loosen the T-Slot transducer assembly with a 1 1/4 inch (32 mm) wrench or socket.
Carefully remove the T-Slot transducer assembly.
4. Place a label on the transducer assembly to marks its location. Port locations are
marked on the transducer cable as well as on cast meter housings.
5. Apply a small amount of Nickel antiseize compound (P/N 3-9960-134) to the
threads of the Hydrotest plug from Hydrotest kit and install it into the mount.
Required kit part numbers are listed below.
6. Repeat Step 3 through Step 5 for the other transducer(s) being careful to note the
location of each transducer in the meter assembly.
7. Run the field hydrostatic test.
8. Reverse the steps above to reinstall the transducers into their appropriate ports.
Before reinstalling the transducer assemblies, ensure the transducer ports, mounts,
and transducer holders are clean and free of debris. Apply a small amount of Nickel
antiseize compound to the outer threads of the transducer holders before installing
them into the mounts.

1.3 Routine maintenance
Routine maintenance operations requires adherence to all applicable regulations and laws
and safety training for personnel to perform the maintenance operations. Review your
organization's best practices procedures before performing routine maintenance.

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 1-2: 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

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 1-3: 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
