Installation of Stack
Flanges
Observe the following instructions and guidelines when installing the OPM
3000 transceiver and retro reflector at the stack.
NOTE
The beam of the instrument must be kept in a horizontal plane; the transceiver
cannot be rotated more than ±10
installed vertically level.
Mounting on Stack Diameters Under 6 Feet
NOTE
Flanges should be mounted approximately 5 feet (1,5 m) up from the deck of
the platforms, roof or walk way.
1. Form two mounting holes in the stack at locations specified in
"Installation Considerations". Holes must be on the same horizontal and
vertical axes. A liquid level can be used to ensure that modules are
installed on the same horizontal plane.
2. Insert a piece of 2-1/2 in. (64 mm) pipe through the mounting holes.
Make sure pipe is protruding far enough to allow installation of the 3 in.
pipe flange assemblies over each end (Figure 2-3, Stacks Under 6 Feet
Across).
NOTE
The customer is required to supply and install two 3 in. IPS flanges at eye
level directly across from each other.
3. The flanges must be aligned so that the total deviation of the light
source flange relative to a common centerline does not exceed ±1
the retro reflector flange does not exceed ±3
these limits can be countered during the installation and alignment of
the light source and retro reflector with the system's alignment
adjustments.
4. Weld the pipe flanges to the mounting nipples, as shown in Figure 2-4.
5. Install the pipe flange assemblies into the stack / duct wall. The flange
should be 6 to 8 in. (152 to 203 mm) from the stack or insulation
(Figure 2-4).
Mounting on
Stack Diameters Over 6 Feet
1. Form two mounting holes in the stack at locations specified in
"Installation Considerations". Holes must be on the same horizontal and
vertical axes. A liquid level can be used to ensure that modules are
installed on the same horizontal plane.
2. Locate one 3-1/2 in. (89 mm) diameter hole (large enough to accept the
3 in. mounting nipple) and the other hole approximately 1/2 in. (13 mm)
diameter, directly across from each other.
