Transducer removal and installation

6.
For all other transducers, place three drops of Dow Corning 200
1
Silicon Oil (12,500
Centistokes) (P/N 1-360-01-650) on the face of the transducer to be installed.
7.
Place the new transducer into the transducer housing. Rotate the transducer so that
the alignment notch on the back of the transducer fits over the indexing pin on the back
of the transducer housing.
8.
Screw the transducer retainer onto the back of the transducer housing. Ensure the
transducer housing threads are properly aligned (avoid cross-threading the housing)
with the meter body, then use a wrench on the 1inch hex bolt, if necessary, to screw it
down until it is flush with the transducer housing. The transducer retainer just has to be
flush and should not be torqued down once it bottoms out.
9.
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. Insert the transducer
cable assembly into the housing in the meter body

10.
Repeat these steps for any other transducers that require replacement.
11.
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
(
).
12.
Once the transducer replacement is complete, use Daniel MeterLink
Calibration|Zero Calibration
and select the Zero Calibration utility to re-zero the meter
at no-flow conditions.
13.
Close your connection to Daniel CUI and install security seals on the transducers if
required (

This completes the transducer removal and installation procedure.
