2.3.4 Attaching the guide rail to the pipe
1.
Remove the two nylon flags from the guide
rail.
2.
Position the guide rail horizontally on the
pipe at 45° to the horizontal and secure in
position using the stainless steel banding as
shown in
Figure 2.5
.
Note: In the following procedure the guide rail is
installed with the rectangular opening facing
towards the upstream end of the pipe.
2.3.5 Fitting the transducers
1.
Attach the nylon flags to the
two transducers, as shown in
Figure 2.6
.
2.
Using a syringe applicator,
apply a 3mm bead of acoustic
couplant to the base of both
transducers.
3.
Insert the downstream
transducer cable (blue)
through the right-hand guide
rail end plate and up through
the rectangular opening at the
left-hand side of the guide rail,
as shown in
Figure 2.7
.
Note: When carrying out the following steps handle the transducer assembly with care to avoid smearing
the couplant on the pipe whilst attaching the transducer to the guide rail.
4.
Connect the downstream cable to one of the transducers and lower the transducer and cable through the
rectangular opening, as shown in
Figure 2.8
.
5.
Align the slots in the side of the nylon flag with the edges on the top of the guide rail then carefully slide
the transducer assembly to the middle of the guide rail.
6.
Tighten the thumb screw (clockwise) until the transducer is locked to the top of the guide rail (to avoid the
acoustic couplant from touching the pipe).
