Direct Mass Measurement of Landfill Gas with Thermal Mass Flowmeters

Fox Thermal Landfill Applications

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:

  1. Fueling on-site engines or turbines
  2. Generating electricity for surrounding homes and businesses
  3. 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.

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.

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.

Fox Thermal strives to design and manufacture the most innovative and reliable thermal mass flow meter products to our customers. All Fox Thermal meters measure mass flow rate and are available in insertion and inline models. Fox Thermal models FT1, FT2A and FT3 are mass flow meters and temperature transmitters providing isolated 4-20mA and pulse output for flow rate, and a 4-20mA pulse output for process gas temperature or a second flow rate output.

Fox Thermal flow meters are often calibrated to measure mixed gases. Please review the product features for Models FT1, FT2A and FT3 for further information about our thermal mass flow meter products.
