2Introduction
2.1 System Overview
The Quasar 8100-EXP Pilot Monitor (PM), Flare Monitor (FM), and Smoke Monitor (SM) are
unique monitoring and detection instruments designed for continuous duty monitoring of Pilot
Flame, Flaring and Smoke on Flares.
The heart of the LumaSense E2TQUASAR M8100-EXP Flare Monitoring System is the non-contact
infrared Electro-Optical package, which can be removed from the explosion proof housing for
repairs or replacement, while leaving all wiring and alignment of the system intact
(see Figure 1).
Figure 1: M8100 Housing and Electro-Optical Package

E2T QUASAR Flare Monitors Operation Manual Introduction •12
A sight-through optical system and selection of various optical resolutions (fields of view) enable
the QUASAR M8100-EXP to be positioned as far as 1/4 mile (400 m) from the stack being
monitored. Alignment on the target is accomplished using exceptional sight-through optics and
the M-3 Heavy Duty Swivel Mount.
Figure 2: Quasar M8100-EXP
The electronics allow for target movement, varying luminosity and a range of climate
conditions. The alarm contact closure delay can be adjusted for a specific location or application,
eliminating false alarms due to intermittent flames, wind, and/or transitory high smoke levels. A
single internally heated detector assures long-term stability and drift-free operation. The system
is complete with internal cooling base, air purge tube and swivel mount. An optional adjustable
pedestal stand allows for easy mounting.
2.2 System Features
Features of the QUASAR M8100-EXP Flare Monitoring System are as follows:
•Explosion-proof housing.
•4 … 20 mA output.
•The Quasar 8100-EXP PM & FM provide a switched 4mA (Flame) or 20mA (No Flame)
switched mA output.
•The Quasar 8100-EXP SM provides a mA span determined by the flame size of the
target flaring event. (Note: every span will be different for different flare
applications)
•On-board ALARM set point with normally open N.O. and normally closed N.C. relay
outputs. This Alarm Setpoint is delayed in the PM/FM from 2 seconds to 2 minutes.
The SM system has no delay.
•Climatic compensation adjustments.
•An Electro-Optical package that is easy to remove from the explosion-proof
housing, minimizing downtime and increasing reliability (see Figure 1).
•An internal heater and water/air cooler cavity for ambient temperature
compensation.
•High quality sight-through optics.
•Local status indication lights.

E2T QUASAR Flare Monitors Operation Manual Introduction •13
2.3 Principle of Operation
All objects above absolute zero emit infrared energy. The amount of energy emitted is
proportional to the body’s temperature. The QUASAR M8100-EXP collects this energy by means
of a focusing optical system concentrating the energy from a body onto a sensitive infrared
detector. Specialized amplification circuitry converts the signal received by the detector into a
DC level to activate relay and mA outputs for monitoring. The M8100-EXP utilizes amplitude
correction circuitry which, when initially set, will automatically correct for diminishing radiation
amplitude due to varying and/or adverse weather conditions.
2.3.1 Alarm Set Point
PM/FM - If the instrument detects a loss of signal fault, an adjustable delay timing circuit starts a
countdown to activate a “loss of signal” alarm. This delay circuit allows for loss of signal due to
wind or adverse conditions for a time period of two seconds to two minutes. This allows the
monitor to reacquire the flame before an alarm signal is sent, limiting false alarms due to
weather conditions. The alarm provides status by LED and Relay contacts.
SM - The alarm set point has no delay and activates in real time.
2.3.2 Relay Contacts
Denoted by their non-energized states, Normal Open (N.O.) and Normal Closed (N.C.) contacts
are common to a single Relay Common (Com), also known as “single pole double throw”
contacts.
4-20mA Outputs
•PM & FM: 4 or 20mA circuit outputs 4mA or 20mA depending on a preset signal level.
Standard output provides 4mA with a flame present, 20mA without a flame present.
This is a switched output.
•SM: mA circuit outputs a signal proportional to the relative amount of smoke detected.
2.4 Signal Path
Infrared (IR) energy is focused onto the detector through a rotating chopper wheel. The
chopper wheel provides the ability to stabilize and improve noise rejection. IR filters are
employed for the FM, PM, and SM models. By virtue of these select, application-specific IR filters,
the desired IR energy is allowed to pass and be amplified by the detector. Filters are located on
the chopper wheel for the SM and are located on the detector for the FM and PM.
The rotating chopper wheel creates a pulsing (on/off) signal, which is then selectively amplified
by the detector. The detector’s amplified signal is conditioned by chopper synchronized,
automatic amplitude control and stabilization circuits. This allows for compensation for
diminishing IR radiation due to climate conditions and is accomplished without operator
intervention.
After the signal is conditioned, it is further filtered and provides the input to subsequent; relay
driver, time delay and 4 … 20mA output control circuits.
2.4.1 SM: Smoke Monitor’s Dual Wavelength (2 color)
Unique to the QUASAR M8100SM-EXP is the use of 2 filters at separate wavelengths or colors.
These filters located on the chopper wheel, allow the electronics to selectively amplify the IR
energy of interest over the background IR energy, thus allowing the Smoke Monitor to
distinguish particulate (smoke) from the background flame that is present.

E2T QUASAR Flare Monitors Operation Manual Introduction •14
2.4.2 PM: Pilot Monitor’s Flame Sensitive Wavelength
The QUASAR M8100PM-EXP uses a single select filter allowing the electronics to amplify the IR
energy of interests over the background IR energy. This allows the Pilot Monitor to achieve high
sensitivity and dynamic range.
2.4.3 FM: Flare Monitor’s Flame Sensitive Wavelength
The QUASAR M8100FM-EXP uses a single select filter allowing the electronics to amplify the IR
energy of interests over the background IR energy. This allows the Flare Monitor to achieve high
sensitivity and dynamic range.

3Mechanical Installation
3.1 Getting Started
Each LumaSense E2TQUASAR M8100-EXP instrument is configured as per customer’s request.
The packing slip order number matches that of the instrument’s serial number. It is
recommended to confirm that the instrument’s configuration meets expectation, by reviewing
packing slip details.
Once you have determined the unit you received is the unit you ordered and it is in acceptable
condition, the unit is ready for installation. It would be a good idea to spend a few minutes
"getting to know" your QUASAR M8100-EXP.
Reference: Chapter 10 Safety Assurances and Precautions.
3.2 Sight Assessment
Care must be taken during installation to ensure that the sun will not be seen through the
optical sight path in any season or time of day. This requires that the instrument be located on a
true north-south axis ± 45 °. In the northern hemisphere, the monitor preferably should be
looking toward true north, while in the southern hemisphere it should be aimed toward true
south. Contact LumaSense for exceptions to these standard installation parameters.
Figure 3: Field of View Concept
3.2.1 Pilot Monitor (PM) 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 include the
Pilot flames and have a spot size of 1.5x to 2x the flare diameter.

E2T QUASAR Flare Monitors Operation Manual Mechanical Installation •18
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.

Figure 5: Pedestal Mounting Concept
3.3 Ambient Temperature Limits
The ambient operating temperature limits of the QUASAR M8100-EXP are -40 °F (-40 °C) to
120 °F (50 °C). When the internal temperature drops below 40 °F (4 °C), an internal electric
heater activates to keep the internal temperature at or above 40 °F (4 °C). If the ambient
temperature is expected to be below -40 °F (-40 °C), additional heating or protection for the
instrument is required. If the ambient temperature is expected to be above 120 °F (50 °C), water
or Vortex Air cooling is required.
3.4 Cooling Requirements
If ambient temperatures in excess of 120 °F (50 °C) are anticipated during the operation of the
QUASAR M8100-EXP, cooling will be required by one of the following two methods:
3.4.1 Water Cooling
Provide cooling water at 60 °F (15 °C) maximum from a filtered source with a flow rate capable
of sustaining at least 10 gallons per hour (37.8 L/h) to the cooling cavity built into the underside
of the explosion-proof enclosure. This method allows operation in ambient temperatures up to
200 °F (93 °C). If the available cooling water temperature is above 60 °F (15 °C), then trial-and-
error testing will have to be performed to empirically set the appropriate flow rate. The flow
rate must be adequate to ensure that the electronics inside the explosion-proof enclosure do
not rise above 120 °F (50 °C).

Note: The cooling cavity is isolated from internal surface of explosion-proof
enclosure. See Appendix E Engineering Drawing 613-816, Service Connections.
3.4.2 Vortex Air Cooling
Connect a V208-15-H Vortex Air cooler to the cooling cavity built into the underside of the
explosion-proof enclosure. Provide filtered, dry, compressed air from a minimum 90 psig source
with a sustained flow rate capability of at least 10 SCFM to the vortex air cooler. This will result
in a temperature reduction up to 27 °F (3 °C) lower than the supply air. It is not necessary to over
cool the instrument. Instead, reduce the enclosure temperature to its specified operating limits
by adjusting the upstream pressure to the Vortex Cooler. If over cooling does occur, the heater
built into the system will activate and keep the electronics within limits.
Note: The cooling cavity is isolated from internal surface of explosion-proof
enclosure. See Appendix E Engineering Drawing 613-816, Service Connections.
3.5 Viewport Air Purge Requirements
A source of sustained dry instrument air with a flow rate through a regulator or needle valve
capable of sustaining 1 SCFM flow rate from a 20 psig or greater supply is required to keep the
lens clean.
3.6 Target Size and Focusing Range
The target size of the QUASAR M8100-EXP is a function of the distance from the lens to the
object under observation and the optical resolution set at the factory. The target area is a circle
reticle as viewed through the QUASAR M8100-EXP's sight-through optics. The diameter of the
detection area (Target Size) is represented by the reticle circle and is calculated using the
formula:
Target Size = D
R
Where D = the distance from the lens to the target.
R = the appropriate value from the following table
The resolution of the optics is application-
specific and determined at time of order.

3.7 Focusing on the Target (Adjust Lens)
The objective lens locking and focusing screw and the eyepiece are both located on the top of
the infrared electro-optical package inside the explosion-proof enclosure (see Figure 6).
To focus, first rotate the eyepiece lens (Figure 6, item 1) in or out until the reticle is clear and
sharp. Next, slowly loosen the lens locking and focusing screw (see Figure 6, item 2). Move the
objective lens (see Figure 6, item 3) in or out with the focusing screw until the target is clear and
sharp. Tighten the screw; the focus is now set.
