Willliamson Model FM-17-EXP Flare Monitor for Hazardous Area Classification

The Williamson Flare Monitor (FM) utilizes proven dual-wavelength technology to monitor the ratio of carbon to available oxygen deep within the hot flare flame. This ratio value correlates to combustion efficiency and is used to adjust the flow of air or steam to smokeless flares, thus assuring smoke-free operation and maximum combustion efficiency.

Assures smoke-free operation and maximum destruction of VOC gasses
One control setpoint for all hydrocarbon (H-C) vent gasses means no on-site calibration
Uninfluenced by flame size or position within the field of view
Uninfluenced by flame composition for all H-C gasses
Unaffected by stack configuration or presence of steam
Includes extra measured parameter values for confirmation and diagnostics
May be grade-mounted for easy access
Used for Manual or Automatic feedback to control steam or air flow
