C. 3410 Series Ultrasonic Meter transducer port
D. Transducer mount and transducer chordset
10. Repeat Step 1 through Step 9 for all transducer holders to be replaced.
11. Slowly repressurize the meter to line pressure. Check for leaks as the meter is
pressurized. If you hear gas leaking from the threads, recheck all connections and
resolve the problem. Then, slowly repressurize the meter to line pressure.
12. Connect to the meter with Daniel MeterLink and update the transducer parameters.
From the Tools → Transducer Swap-out menu, run the Transducer Swap-out
Wizard. This utility allows you to update the parameters for the components that
are replaced.
Note
Running the Transducer Swap-out utility is required when transducers, mounts,
holders, or stalks are replaced for a chord.
a) After writing all of the changes to the meter’s configuration, open the
Monitor (Detailed View) and verity the meter is acquiring data, the
transducers have good signals and flow profiles for the all of the chords
displayed.
b) Collect and save a Maintenance Log and verify the meter is optimally
performing. Save the meter configuration file. If communicating with the
meter via Modbus or HART, manually update the parameters (see Modifying
the calibration parameters for T-Slot transducers).
