Flarespection IR camera system

Yes, provided each flame occupies a resolvable area within the camera view. The 640 × 480 uncooled microbolometer, 17 µm pixel pitch and 200 mm telephoto lens provide a 3° × 2.3° field of view, allowing the software to separate heat signatures within the scene. Individual pilots can be monitored while the main flame is present, and the system is intended for multiple-pilot or closely spaced flare arrangements. Scene-registration tools can maintain analysis alignment when the stack moves or sways. Camera quantity and viewpoints should still be determined from stack geometry, pilot orientation, wind movement and possible line-of-sight obstructions.

The camera can monitor from distances up to 300 m, but its final position should be established through a site survey. The 200 mm lens and 3° × 2.3° field of view create a narrow viewing area, so the selected location must provide clear coverage of every required pilot and flare region. The survey should record the stack height, flare-tip orientation, number of pilots, proposed camera distance, prevailing wind direction, hazardous-area classification and ambient temperature. A rigid mounting foundation is important because small angular changes become more significant over long distances. Complex stacks may require several viewpoints rather than one camera.

Yes, when the installation classification matches the stated approvals and environmental limits. The system carries ATEX II 2 G Ex db IIB T4 and IECEx Ex db IIB T4 classifications, together with US and Canadian Class 1 Division 1 and Division 2 ratings for the listed gas groups. Its 316L stainless-steel housing is rated NEMA 4X and IP66, with a specified operating range of -30 to 50°C. The project engineer must still verify the applicable gas group, temperature class, division or zone, cable entries, power arrangements and local installation rules. The enclosure rating should not be treated as automatic approval for every classified location.

The system supports OPC, Modbus serial, Modbus Ethernet, analogue contact outputs and relays. These interfaces allow pilot status, flare condition, alarms and processed image results to be passed to a plant DCS, PLC or pilot ignition arrangement. The camera system requires a 24 VDC power input, while an optional I/O module can provide connections for hard-wired control and alarm functions. Files and processed data can also be transferred to a data historian when the appropriate server and database architecture are installed. The selected interface should match the required response, redundancy, cybersecurity and plant-standard communication practices.

It can be engineered as an independent, non-contact monitoring method or as a backup to conventional thermocouples. Because it observes heat signatures remotely, it can continue reporting pilot and flare status when a thermocouple at the flare tip fails. It also avoids placing the primary sensing device directly within the flare-stack environment and can monitor several pilots from one or more ground-mounted locations. However, replacing an existing protection or control instrument requires a site-specific functional safety and regulatory assessment. Alarm logic, voting arrangements, proof testing and failure responses should be defined before the thermal imaging signal is assigned a safety-related role.

A Windows-based host is required for live image acquisition, automated analysis, alarm handling and archiving. The software can support up to 24 cameras, allowing several flare views to be displayed and managed from a central workstation or plant network. Recorded images, video, events and alarm data may be archived to files or a database, while an optional server and SQL-based historian can support longer-term storage. Scene registration helps maintain image-analysis alignment when the stack moves, and plant interfaces can deliver processed results to the DCS or PLC. Storage capacity, network bandwidth, user access and software licence level should be defined during system design.

The standard scope includes the FlareSpection camera with a 200 mm lens, a stainless-steel enclosure with sunshield and sight tube, flare and pilot monitoring software, and an adjustable stainless-steel pan-and-tilt mount. Optional equipment includes a stainless-steel base, field junction box, I/O module, automation server and SQL-based data historian. These options affect the mechanical installation, cable marshalling, control-system interface and data-retention architecture. Projects involving several cameras may also require network switches, additional server resources and suitable operator displays. The final bill of materials should therefore be based on the number of viewpoints, required outputs and plant-network arrangement.

Remote mounting and the integrated sight tube reduce routine access requirements, but they do not remove the need for inspection. Maintenance planning should cover window cleanliness, sight-tube condition, mounting security, alignment, enclosure seals, cable entries, network health and alarm operation. The adjustable stainless-steel mount and scene-registration function help preserve the monitoring view, while the NEMA 4X, IP66 and 316L construction protect the installed hardware. Any work within a hazardous area must follow the site’s permit, isolation and inspection procedures. Inspection and functional-test intervals should be selected according to environmental exposure, process criticality and the role assigned to each alarm.
