6. Repeat Step3 through Step5 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.
1.2.2 T-200 transducer assembly
The T-200 transducer assembly has full-metal structure and can remain in place during
field hydrostatic pressure test.
Procedure
1. Leave T-200 transducers installed on the Rosemount 3410 Series Gas Ultrasonic
Meter while the line is pressurized.
2. Run the field hydrostatic test.
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, it is recommended to perform routine diagnostics.
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. Go to Logs/Reports
→ 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 Start. 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 is 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).
