Pipe Targets 6.4
The correct target you use depends on the elevation of the laser beam above
the pipe invert and your personal preference.
Through the Pipe Applications 6.4.1
For pipes with a diameter of 500 mm (21 inches) or less, the laser beam is
normally projected on the centerline of the pipe. When the target is
calibrated to the pipe’s diameter, the target may be used in any orientation
in the pipe to maintain the target’s bull’s-eye on center with the pipe.
When the laser is set above the flow-line other than the pipe’s centerline,
the target must be leveled in the pipe. If the target is not level, the pipe may
be placed off line or grade.
