T-200 transducer capsule assembly (see Figure 3-9) can be removed or installed while the
line is pressurized or at atmospheric pressure.
3.5.1 T-200 transducer capsule assembly removal
This procedure is for removing a transducer capsule assembly from a T-200 transducer
assembly installed in a meter body. The line can be pressurized or at atmospheric pressure.
Procedure
1. Disconnect transducer cabling and chordset from the T-200 transducer assembly by
turning the cable nut counter-clock wise.
2. 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.
3. Remove the transducer retainer from the transducer stalk by turning the retainer
counter-clock wise with a 1 ⅛” wrench.
4. Hold the transducer capsule assembly and carefully pull it out of the transducer
stalk.
Note
Do not remove the Kapton tape on the top of the transducer capsule assembly.
5. Use non-fiber paper to remove any residue of acoustic coupling fluid on the surface
of Kapton tape.
6. Record the serial number of the removed transducer capsule assembly and put it in
a safe place.
7. Repeat Step 1 to Step 6 if more transducer capsule assemblies are to be removed.
3.5.2
