Flue Gas Monitoring

Stack Gas Monitoring and Air Flow Emissions

Flue gas monitoring is often required for environmental reporting, and thermal mass flow meters offer a reliable means to measure and monitor flue gases which contain greenhouse gas.

Many industrial processes in chemical and food processing, power plants, boilers and metal operations dissipate flue gases.

What Are Flue Gases?

Flue gases are byproducts of the combustion process, and usually consist of nitrogen and carbon dioxide with traces of sulfur dioxide, nitrogen oxides, carbon monoxide, other trace gases and miscellaneous particulates. Many industrial processes in chemical and food processing, power plants, boilers and metal operations dissipate flue gases.

Process Venting Requires Flow Metering for EPA Reporting

Most flue gas generally contains pollutants, and as such is regulated by local or regional air quality districts and/or the federal government. Thus the stacks, ducts, chimneys large pipes or other process system venting often require flow metering to comply with environmental reporting.

Flue Gas Monitor with Thermal Flow Meters

Sage Prime Insertion Style Thermal Mass Flow Meters provide the wide turndown required to cover both the extremely low flows (low velocities) associated with normal venting, as well as the extremely high flow (high velocities) associated with wide swings in output. Their fast response to flow changes, low-pressure drop, and reproducibility are important characteristics for a flue gas reporting application. In addition, Sage Flow Meters provide the customer with a unique in-situ calibration check at a “no flow” (0 SCFM) condition. This important procedure, assures that the flow meter has retained the original NIST Traceable calibration, verifies the meter’s accuracy, confirms that the sensors are clean and that the flow meter hasn’t drifted or shifted. This is a tremendous benefit since it eliminates the cost and inconvenience of annual calibrations on the flow meter, and also provides the data needed to comply with a number of environmental protocols.
