The E2T M8100SM provides continuous monitoring of flare stack smoke levels for smokiness operation of flare stack flames and enables control of smokeless steam inlet valves.

The Quasar M8100 utilizes multi-wavelength infrared detection and electronic circuitry to automatically compensate for signal variation due to rain, snow or fog. Observed flaring is reported via a 4 to 20 mA signal.

The instrument can be mounted on a control center roof and sighted to monitor flaring on distant flare stacks. It is available with a sturdy mounting system designed to resist movement in high winds and provide vernier sighting capabilities for easy target acquisition at long sighting distances.


  • Install a reliable and accurate flare smoke monitoring system without service interruption
  • Use the high-resolution optical system and various spot sizes to position the system up to 1/4 mile (400 m) away from the monitored flare stack
  • Minimize weather impacts with automatic gain control
  • Increase safety and environmental protection



  • Custom electronics adapt to target movement, varying luminosity, and most climate conditions
  • Five optics options to ensure the highest flame signal detection
  • Status lights: green and red
  • Heavy-duty swivel mount included for easy mounting, alignment, and target focusing
