Landfill Gas (LFG) contains methane, a potent greenhouse gas.
The EPA requires landfill operators to collect the methane produced on site, and where it is not being used for energy production, it must be flared to prevent its release.
Landfill Gas to Energy (LFGTE) facilities typically extract gases from multiple wellheads, which are connected to a common header pipe, and then recovered for a variety of uses, including:
- Fueling on-site engines or turbines
- Generating electricity for surrounding homes and businesses
- Conversion to Liquid Natural Gas, a clean vehicle fuel
Accurate landfill gas monitoring is essential for gathering system-wide information on the amount of gas being extracted, flared or recovered. Some of the measurement challenges in the LFG environment are changing gas compositions, varying flow rates caused by seasonal temperature changes, and wet, dirty and potentially flammable gases.

Fox Thermal Mass Flow Meters can help LFGTE operators comply with clean air regulations, as well as improve the operation of co-gen engines or methane oxidizers. With turndowns from 100:1, specified accuracy of +/- 1% of reading plus .2% of full scale, and repeatability of +/- .2% of full scale, Fox Thermal Flow Meters exceed the requirements of EPA's 40 CFR Part 98 Subpart HH and Subpart TT.
Gas-SelectX® for Superior Landfill Gas Monitoring
Landfill gas composition tends to change over time. You'll need a more flexible solution to maintain an accurate record of LFG flow. Models FT1, FT4A, and FT4X are versatile flow meters that can be programmed in the field using Gas-SelectX®. As the gas composition changes, simply access the gas composition settings in Gas-SelectX® to reprogram the percentages of component gases and avoid sending the flow meter back to the factory to be recalibrated. Keeping your process running with a flexible and accurate flow meter from Fox Thermal will help you Make Downtime a Thing of the Past. See our Fox Thermal Product Comparison for more specific information on how a Fox Thermal flow meter can work for your application.
