22 Steps to remove a transducer assembly from a meter while the meter is under line pressure
Section 4: Removing a transducer assembly Operation Manual

m. To check the sealing integrity of the extractor tool valve assembly (H), close the
lubricator chamber vent valve (R). Wait several minutes and observe lubricator
chamber pressure gauge (T). If zero pressure is indicated by the gauge, this
confirms that sealing is successful. Open the lubricator chamber vent valve (R).
7. Refer to Drawing D-08248 DETAIL “G” (Appendix C).
a. Remove the meter housing quick connect stem and reducer if it was required.
Return the parts to the tool kit.
b. Disconnect the high pressure hose quick connect body (AA) from quick connect
stem (FF) on the ultrasonic meter housing line pressure valve (Q). Disconnect the
high pressure hose quick connect body (AA) from quick connect stem (CC) on
the pressure regulator (V) high pressure (primary) port.
c. Disconnect the low pressure hose quick connect body (BB) from the quick
connect stem (DD) on the pressure regulator (V) low (secondary) pressure port.
Wrap the low pressure hose around the extractor tool piston assembly (P) and
connect the low pressure hose quick connect body (BB) to the quick connect
stem (EE) located on the extractor tool piston assembly (P) flange for storage.
8. Refer to Drawing CE-21065 DETAIL “F” (Appendix C).
a. Loosen and remove the four extractor tool piston assembly (P) nuts (X) from the
flange on the lubricator chamber assembly (M). Minimize the rotation of the
extractor tool assembly during nut removal. Remove the extractor tool piston
assembly (P) from the lubricator chamber assembly (M). For safe keeping
reinstall the nuts (X) after removal.
SEALING HAZARD
If the lubricator chamber pressure gauge (T) indicates pressure in the lubricator chamber
assembly (M) after a period of time, the extractor tool valve assembly (H) seals may be
leaking. If this is observed proceed to Section 4.1, Step 1A) of the instructions “Steps to
install a transducer assembly while the meter is under line pressure” and re-install the
transducer holder (K).
Failure to repair all leaks could result in personal injury from explosive forces or asphyxiation.
