CAUTION
LEAKAGE OR PRESSURE CONTAINING PARTS FAILURE
Use precautions to eliminate hazards to personnel in the event of leakage or failure of the
gas ultrasonic meter pressure containing parts or failure of the test equipment and to
prevent over-pressurization during the test procedure.
Failure to comply may result in injury to personnel or cause damage to the equipment.
1.2.1
T-Slot transducer assembly and mount
Procedure
1. Slowly vent all line pressure on the 3410 Series Gas Ultrasonic Meter to atmosphere.
2. Disconnect transducer cable from the transducer holder.
3. Loosen the T-Slot transducer assembly with a 1 1/4 inch (32 mm) wrench or socket.
Carefully remove the T-Slot transducer assembly.
4. Place a label on the transducer assembly to marks its location. Port locations are
marked on the transducer cable as well as on cast meter housings.
5. Apply a small amount of Nickel antiseize compound (P/N 3-9960-134) to the
threads of the Hydrotest plug from Hydrotest kit and install it into the mount.
Required kit part numbers are listed below.
6. Repeat
for the other transducer(s) being careful to note the
location of each transducer in the meter assembly.
7. Run the field hydrostatic test.
8. Reverse the steps above to reinstall the transducers into their appropriate ports.
Before reinstalling the transducer assemblies, ensure the transducer ports, mounts,
and transducer holders are clean and free of debris. Apply a small amount of Nickel
antiseize compound to the outer threads of the transducer holders before installing
them into the mounts.
