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 condition-
ing 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
transducers. Attach the other ends to the flowmeter’s UP and DN terminals. See Engineer-
ing Drawing 1010BX-7, Single Channel or 1010BDX-7 Dual-Channel.
7. You can now press <ENT> 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.
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 assembly 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.
3.3.9 REFLECT MODE WITH SPACER BAR ONLY
The spacer bar eliminates manual spacing measurements and provides rigidity for mounting
the transducers while maintaining axial alignment.
