2.6.1 Even Number of Traverse Method
Note:
The instructions in this section can also be used for a multiple-traverse method. However, you must use
an
EVEN
number of traverses. The distance the signal travels from one side of the pipe wall to the
opposite side of the pipe wall is considered one traverse. For installations with more than two traverses,
contact BHGE for assistance.
The installation procedure for transducers using the even number of-traverse method is as follows:
1.
Ensure the location of your clamping fixture has been properly scoped out following the criteria in
Section 2.6: Precautions.
2.
Prepare the pipe where you intend to place the clamping fixture by making sure it is clean and free of
loose material. Sanding, though usually not required, may be necessary to remove any high spots.
However, be careful to preserve the original curvature of the pipe.
3.
Secure one of the blocks to the alignment bar by tightening one of the nuts on the block so the block
will not be able to slide along the alignment bar's slot.
4.
Obtain the transducer spacing dimension (S) after programming the XMT1000 transmitter. Using the
alignment bar as a guide, move the second block so that the distance between the blocks equals the S
dimension. Use the pressure bolts or the edges of the blocks as reference points, as shown below
Figure 8: SCF Setup, Spacing
5.
Position the clamping fixture on top of the pipe and wrap the clamping fixture blocks with the hose
clamps. Tighten the clamps until the blocks are snug but ensure that they can still be rotated around
the pipe.
6.
Rotate the blocks so that they are away from the vertical plane and in an orientation that satisfies the
criteria listed in Section 2.6: Precautions.
7.
Fully tighten the hose clamps so no movement on the fixture will occur.
