6.2 Mounting the Transducers into the TransFlection Mode Clamping Fixture - TMCF (cont.)
4. Slide the transducer into one of the blocks.
To ensure against impact to the transducer face, it must always be mounted flush to the pipe.
Counter Nut
5. Use the pressure bolt to secure the transducer into place. The pressure bolt should fit into the dimple on the top of
the transducer. Tighten just enough to hold the transducer in place. DO NOT tighten so much that the block lifts off
the pipe.
6. Tighten the counter nut on the pressure bolt (see drawing above).
IMPORTANT:
When using the TMCF in a pipe location with possible mechanical vibration, the locking nut must be used
to secure the position of the pressure bolt on the transducer after the bolt has been hand-tightened into the
transducer dimple. For additional resistance to vibration a thread lock compound or a stainless steel
washer and lock washer may also be used. These items can be ordered from GE by requesting a "special"
clamping fixture and specifying either the thread lock or the washers.
7. Repeat steps 1 through 6 to insert the other transducer into the remaining block. Refer to Figure 15 on page 49 and
Figure 16 on page 50 for examples of completed installations. When inserting the second transducer, make sure the
transducers face the same direction.
