Procedure
1. Blow the line down according to the site standard operating procedures.
2. Ensure that the line pressure is down to atmospheric pressure prior to disassembly.
3. Disconnect the transducer cable nut. Pull the chordset from the transducer
assembly.
Note
Do not twist the chordset as you disconnect it from the transducer assembly (see
Figure 3-7).
4. If the meter is equipped with T-21 or T-22 transducers, remove the transducer
retainer using a 1 1/8” wrench and then disconnect and remove the transformer
(Figure 3-5).
T-21 transducers use W-01 transformers and T-22 transducers use W-02
transformers.
5. Use a 1 1/4” (32 mm) wrench on the hex of the transducer holder and slowly
unscrew in a counterclockwise direction from the meter. If you hear gas leaking
from the threads, immediately stop and reinstall the holder as the meter has not
been fully drained and/ or pressure has not been relieved from the meter. Correct
the issue before attempting to remove the holder.
6. The transducer holder has now been removed from the meter with the transducer
still installed inside the transducer holder.
7. Make a note of the removed transducer holder length which is used to update the
meter configuration during the Transducer Swap-out procedure in Daniel
MeterLink, after all of the transducer holders are replaced.
