August 2014 3-9000-743 Rev U

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 transducer cabling and chordset from the transducer assembly by turning

the cable nut counter-clock wise.

4. Meters with M-mounts or P-mounts, remove the mount cover by loosening the two

mount cover captive screws with a flathead screw driver (see Figure 7-4).

5. 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.

6. 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 7-5).

Note: T-21 transducers use W-01 transformers and T-22 transducers use W-02

transformers.
