3.3.6 Direct Mode Mounting Using Track Mount Hardware
1. Once the installation site selection process described in section 3.2 is complete,
prepare the pipe where the first sensor will be mounted.
2. To prepare the pipe, temporarily position one track mount hardware assembly on each
side of the pipe where you intend to permanently mount them as shown below.
Ensure that pipe surface is smooth without any raised areas (seams, etc.) With a
pencil, marker or chalk, draw a rectangle around each track mount assembly. Remove
the hardware from the pipe and clean and de-grease the area within the rectangles. Use
the small sanding block provided with the installation hardware as necessary to
remove any grit, corrosion, rust, loose paint or other contaminants. Be sure to wipe
the surface clean after sanding. The cleaned surface should extend at least ½” beyond
the length and width of each assembly.
3. Re-install the two track mount hardware assemblies on the pipe and loosely secure
them in place with the mounting straps provided. Align the assemblies such that they
are positioned on top of the cleaned surfaces.
IMPORTANT NOTE
Direct mode mounting requires that transducers be installed on opposite sides of the pipe. For
horizontal pipes, the transducers should be located at the 3 o’clock and 9 o’clock positions.
