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 adjust-
ing 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 pro-
vided. 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 Engineering Drawing 1010N-7,
Single Channel or 1010DN-7 Dual-Channel.
7. You can now press 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.
