Products
Smokeless Flare Monitor (FM)
The Williamson Smokeless 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.
- Ensures smoke-free operating conditions
- Optimizes combustion efficiency & assist levels
- Can be used to reduce energy costs related to excessive steam/air assist

Pilot Flame Monitor (PM)
Flammable vent gasses are ignited by a pilot flame when released into the atmosphere by chemical and petrochemical plants of all types. The proper incineration of these gasses is a critical safety and environmental concern. Therefore, it is essential to confirm that the pilot is lit at all times.
Monitoring via thermocouple is common, however failures frequently occur and replacements can require costly process shutdowns.
The Williamson Pilot Monitor (PM) utilizes proven dual-wavelength technology to sense the presence of the small, distant pilot flame. This technology allows the pilot monitor to view clearly through severe weather conditions caused by fog, wind, rain, snow and sleet.
- Confirms the presence of a lit pilot flame – even through fog, rain, snow, and sleet
- Can be used as a backup monitoring device for when thermocouples fail
- Mounted at ground level for easy access

Flame Intensity Monitor (FI)
Williamson Flame Intensity Monitors (FI) are the single-wavelength sensors of choice for a variety of flare applications where the more sophisticated dual-wavelength flare products are not appropriate or are not required. This lower-cost technology is also commonly used as a pilot flame detector for ground flares and landfill flares where the viewing distance is less than about 300 feet or 100 meters.
- Used for ground flares or when viewing distance is < 300ft/100m
- Best for H2, CO, or ammonia flames
- Output can be used to determine the difference between pilot flame and flaring conditions

Sulfur Recovery Unit (SRU)
In a petrochemical refinery or natural gas processing plant, sulfur is extracted from the crude oil or natural gas product stream as amine gas, sour water stripper, sulfuric acid and hydrochloric acid. The sulfur is then recovered in the sulfur plant using a thermal reactor called a Sulfur Recovery Unit (SRU), also known as a Claus reactor. Accurate temperature measurement allows for maximum amine acid gas and sour water stripper gas throughput without overheating the refractory wall. This assures a safe operating condition and extends refractory life. The Williamson SRU sensors are used to replace troublesome thermocouples which can not survive this hostile, acidic environment.
- Fiber optic configuration eliminates the need for active cooling
- Warm flange mounting reduces/eliminates sulfur deposition in the optical path
- Option to measure either gas temperature or wall temperature
