3.2.2 Flare Monitor (FM) Sighting
Recommended installation distance should be equal to the height of the flare stack from the
base of the flare stack. The maximum vertical angle for sighting the monitor is 45 ° above
horizontal. (See Appendix E Engineering Drawing 613-228.)
Targeting should be just above the pilot flames, so that they are not included in the
measurement, or if this is not possible, then the gain should be reduced until the pilot flames
are not detected. The spot size of the system should be 3x to 4x the flare tip diameter.
3.2.3 Smoke Monitor (SM) Sighting
Recommended installation distance from the base of the stack is at least 1 to 2 times the stack
height. The maximum vertical angle for sighting the monitor is 45 ° above horizontal. The field
of view must be at least 4 to 5 times the stack top diameter when no wind is present.
3.2.4 Mounting Options
For easy mounting, alignment, and focusing on the target, a swivel mount with locking and
adjusting capability is provided (LumaSense’s M-3 Heavy Duty Swivel Mount). The M-3 Heavy
Duty Swivel Mount can be secured on a pedestal base model M-8 using a telescoping steel pipe
with a bolt down plate to secure the M-8 to a foundation. (See Figure 5) As an alternative, the
M-3 Heavy Duty Swivel Mount can be installed on a client supplied 2-inch schedule 40 pipe
mount.
