2. On a flat surface, attach the spacer bar to a mounting frame so that the reference hole on the
spacer bar fits over the post on the platform of the frame; tighten the securing screw. Slide the
second mounting frame onto the other end of the spacer bar, align the number index hole with the
post on the platform; then tighten the securing screw. Ensure that the angled sides of both frames
face away from each other. At the mounting location, place the mounting frame/spacer bar assem-
bly on the pipe so that it rests on the top of the pipe. Wrap a mounting strap around the pipe.
Engage the end of the mounting strap with the mounting strap adjusting screw. Slide it under the
spring clip (if so equipped) of one of the mounting frames. Make sure to position it for easy access
to the mounting strap adjusting screw. Do the same to the other mounting frame.
3. Tighten the mounting strap screw enough to take up all of the slack, but not enough to prevent
rotation of the assembly. Rotate the assembly on the pipe to the 9 o’clock position ensuring that it
is a smooth area without any raised spots or seams. Mark a generous area around the mounting
frames (1/2” on either side and half again the length front and back) with a pencil or chalk. Move or
revolve the assembly away from the area marked (loosen straps if necessary to do this).
4. Prepare the two areas you marked by de-greasing the surface, if needed, and removing any grit,
corrosion, rust, loose paint or surface irregularities with the abrasive pipe conditioning material
provided. Clean the pipe of all debris and abrasive particles.
5. Reposition the assembly over the center of the prepared surfaces. Tighten the mounting straps to
seat the assembly firmly on the pipe. Do not overtighten.
Apply a continuous 1/8-inch bead of coupling compound to the center of the face of a transducer,
then slide it into the mounting frame but holding it away from making contact with the pipe until it
butts up against the stop (to keep from smearing couplant where it’s not needed); then push down
onto the pipe. Tighten the transducer clamping screw to hold the transducer firmly in place. Repeat
for the other transducer.
6. Observing the upstream to downstream orientation, attach the UP and DN cables to the transduc-
ers. Attach the other ends to the flowmeter’s UP and DN terminals. See Engineering Drawing
1010N-7, Single Channel or 1010DN-7 Dual-Channel.
7. You can now press the <ENT> key to finish the transducer install routine. The available Mounting
Strap kits are listed below. Each kit comes with up to two band sizes to cover its designated pipe
diameter range and a spacing guide for Direct Mount.
3.1.6 REFLECT MODE WITH SPACER BAR ONLY
The spacer bar eliminates manual spacing measurements and provides rigidity for mounting the trans-
ducers while maintaining axial alignment.
