Chapter 6. Microcell Installation on Vertical Pipe Legs
6-2
Horizontal Distribution of Microcell Sets
Microcell sets are placed on each support leg.
Vertical Location of Microcell Sets
Note
Microcell locations may be adjusted up to 12” (305mm) vertically to
avoid obstacles. If adjusting locations, maintain the configuration
of the Microcell set (i.e., if you move one Microcell in the set from
its ideal location, move the other(s) as well).
Pipe Legs without X-Braces
See Figure 6-3.
• If the free leg distance (length between foundation and vessel) is
between minH and 11’ (3.4m), mount the Microcell sets at mid-height
of the free leg.
• If the free leg distance is more than 11’ (3.4m), mount the Microcell
sets at 5’-6” (1.7m) above the foundation.
• If the free leg distance is less than minH, this is a special
application situation. Consult KM before proceeding further.
Pipe Legs with X-Braces
See Figure 6-4. If the free leg distance is minH or more, mount the Micro-
cell sets at mid-height of the free leg.
• Measure the free leg between the bottom of the bottom x-brace or
horizontal brace and the top of the foundation.
• For an alternate location, measure the free leg between the top of the
top x-brace or horizontal brace and the beam supporting the vessel.
See Figure 6-5. If the free leg distance is less than minH, mount the
Microcell sets at the mid-height between the lowest braces.

Note: MinH is
defined as the
minimum free height
to install sensors.
The height should be
three times the pipe
width or 12” (305
mm) whichever is
greater.
