Digester Flow Meters for Monitoring Biogas in Digester Applications

Fox Thermal Digester Gas Applications

Common Biogas Applications

Gases produced from anaerobic digesters are commonly monitored by thermal mass flow meters. Biogas is produced when organic matter decomposes in the absence of oxygen and digesters are often the vessels used in this process. Landfills, farms, and wastewater treatment plants are becoming common sites for the use of digesters to produce biogas.

Typically, biogas is made up of 70% methane and 30% carbon dioxide; however, digester gas is known to change composition from time to time. A remedy for this is to have a portable gas analyzer to check periodically for any changes in the gas composition. If your meter is calibrated to measure a particular mixture, you may encounter accuracy errors if the gas composition changes. The larger the change, the greater the error.



Smart Sense with Gas-SelectX®

Fox Thermal has developed Gas-SelectX® for use in Models FT1, FT4A, and FT4X. The gas components of biogas tend to change from time to time, but most flow meters are calibrated to measure one gas type or one set gas mix. In these cases, you'll need a more flexible solution to keep your process running. 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.



Fox Thermal Flow Meters for Biogas Applications

Thermal gas mass flow meters are often used in digester gas applications, including:

  • Digester gas flowmeters for Livestock manure management systems
  • Swine and dairy farms
  • Liquid systems (lagoons and holding tanks)
  • Digester Gas Meters for Landfills
  • Municipal Solid waste systems
  • Digester Gas Flow Meters for Wastewater Treatment Plants

Flow meters from Fox Thermal offer a wide turndown that provides accurate measurement of the fuel gas produced from digesters. Fox Thermal gas flow meters have a built-in totalizer often used in auditing procedures of greenhouse gas emissions for environmental monitoring and reporting.
