Flue gas monitoring is required for environmental reporting, and thermal mass flow meters offer a reliable means to measure and monitor flue gases containing greenhouse gas.
What Are Flue Gases?
Flue gases are byproducts of the combustion process. Usually, they consist of nitrogen and carbon dioxide with traces of sulfur dioxide, nitrogen oxides, carbon monoxide, other trace gases, and miscellaneous particulates. Many industrial chemical and food processing processes, power plants, boilers, and metal operations dissipate flue gases.
Process Venting Requires Flow Metering for EPA Reporting
Most flue gas generally contains pollutants and is regulated by local or regional air quality districts and 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 and Paramount insertion-style thermal mass flow meters provide the wide turndown required to cover both the extremely low flows (low velocities) associated with standard venting and the high flow (high rates) associated with wide swings in output. Their fast response to flow changes, low-pressure drop, and reproducibility are significant characteristics of a flue gas reporting application. Also, Sage Flow Meters provide the customer with a unique in-situ calibration check at a “no-flow” (0 SCFM) condition. This distinctive 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. It is a tremendous benefit since it eliminates the cost and inconvenience of annual calibrations on the flow meter and provides the data needed to comply with several environmental protocols.
