Important
Record the “L” dimension of the removed transducers which is used to update the
meter configuration after all of the transducers are replaced. Make sure you have
the report sheet containing the “L” dimension, Delay Time, and Delta Delay Time
for the replacement pair of transducers to use during the Transducer Swap-out
procedure in Meterlink.

T-Slot transducer installation
Procedure
1. Ensure that the Rosemount
™
3410 Series Ultrasonic Gas Flow Meter transducer
port, mount, and T-Slot transducer holder assembly are clean and free of debris.
2. Apply a small amount of Molykote 111 to the female contacts on the transducer.
3. Install the transducer assembly into the transducer holder or into the stalk (if
required). The parts are keyed and can only be assembled one way. As the
transducers are installed into the holder or stalk assembly, they must be labeled
with a marker for future reference (i.e., transducer #1 would be A-1 and transducer
#2 would be A-2).
4. Use a 1/16” hex driver to equally tighten the three Allen set screws on the
transducer holder to secure the transducer assembly and the stalks (if installed).
