Advanced Flow Meters for Emissions Monitoring

Identify Gas Leaks

Thermal mass flow meters can help identify leaks with check and sub-meters installed. Not only does this help with facility health and safety standards, but it also improves efficiency and avoids emissions of harmful greenhouse gases.

Gas Emissions Monitoring and Reporting Compliance

Fox Thermal mass flow meters’ accuracy specification exceeds the requirements defined by the EPA and provides a reliable, cost-effective solution to emissions monitoring challenges.

Improve Equipment Efficiency

Fuel gas flow meters can help analyze demand, improve operating efficiency, reduce waste, and adjust for peak usage, while also providing accurate emissions data for environmental and regulatory compliance.

More About Continuous Emissions Monitoring

The U.S. EPA 40 CFR part 98, requires owners or operators of commercial facilities that emit over 25,000 metric tons or more of CO2e (CO2 equivalent in global warming potential) per year of greenhouse gases to monitor and report annual mass emissions.

According to the EPA, a continuous emissions monitoring system (CEMS) consists of the total equipment necessary for the determination of a gas or particulate matter concentration or emissions rate using flue gas analyzer measurements and a conversion equation, graph, or computer program to produce results in units of the applicable emission limitation or standard.

Thermal mass flow meters from Fox Thermal provide accurate measurements of natural gas streams for CEMS calculations from industrial processes, as well as monitoring of methane emissions and other greenhouse gases emitted from landfills, wastewater treatment plants, and oil & gas production.

Fulfilling Government Requirements for Gas Emissions Monitoring

Globally, governments have pledged to reduce greenhouse gas emissions in an effort to slow or halt climate change. To that end, most of the world’s oil and gas production, processing, transportation, and storage entities must provide regular, accurate accounts of air pollution emissions to local, state, and/or national regulatory bodies.

These agencies also have published rules and regulations regarding SO2, nitrous oxide, CO, and other polluting emissions from industrial plants, water and wastewater treatment plants, and landfill gas to energy (LFGTE) operations.

Emissions flow monitoring requires a flow meter that meets the accuracy and periodic calibration verification requirements set by national, state, and/or local environmental agencies.

flow meters are a solution to reducing greenhouse gas emissions

Gas-SelectX® for Superior Emissions Monitoring

All Fox Thermal models can be used for gas emissions monitoring applications. Each model has a range of features and specifications and can be configured according to the process conditions and requirements.

If the gas composition of emissions from your application is expected to change over time, Fox Thermal’s Gas-SelectX® feature, available on models FT1, FT4A, and FT4X, can be a helpful tool for modifying the gas composition percentages in the meter while maintaining the highest accuracy (Note: gases vary by model).

Several other factors may affect the customer’s model choice: approvals, power input requirements, communication protocols, available straight run in the pipe, line sizes, data logger (only available on the FT4X), and pressure ratings, to name a few. The online product configurator below uses these variables to suggest the right model configuration for your needs.
