13. Slide the locking ring onto the transducer housing in an orientation so that the locking
ring bolt can be installed through the slot of the locking ring and into the threaded hole
in the meter body. The recommended torque for installing the locking ring bolt is
2.5 ft-lb (3.4 N-m).

14. Align the transducer cable connector with the indexing key on the back of the
transducer and hand-tighten the coupling nut to secure the cable ( see Figure 3-11 ).
15. Apply power to the meter and slowly repressurize the meter to line pressure. Check for
leaks as the meter is pressurized. If you hear or see fluids leaking from the threads,
recheck all connections and resolve the problem. Then, slowly repressurize the meter
to line pressure.
16. Connect to the meter using Daniel MeterLink. Open the detailed view in Meter Monitor
and verity the meter is acquiring data, the transducers have good signals and flow
profiles for the chords are displayed.
17. Use the
Tools|Transducer Swap-out
menu path to access the Transducer Swap-out
Wizard. The Transducer Swap-Out Wizard is a utility that allows you to easily update
parameters such as path lengths, delay times, and delta times for chord. This is
necessary anytime transducers or housings have to be replaced for a chord. The wizard
guides you through updating which chords have been changed, which components in
the chords have been changed, as well as recalculating new path lengths based on the
information entered. This utility is only available while connected to a meter. Collect
and save a Maintenance Log and verify the meter is optimally performing. If
communicating with the meter via Modbus or HART, manually update the parameters
(
see Section 3.3.1 ).
18. Disconnect communications with the meter and close DUI.
19. If required, install the security wires on the transducer(s) cable and locking ring ( see
Figure 3-7 ) for each component you replaced.
20. This completes the removal and installation of the transducer housing.
