Accurate, Economical Green House Gas Flowmeters

GHG Flow Meter Measures CO2 Equivalent Emissions

To help you comply with the United States Environmental Protection Agency’s (EPA) new industrial greenhouse gas (GHG) emission rule (40 CFR part 98), Sierra offers several certified GHG emissions reduction flowmeters that calculate CO2-equivalent emissions.

The EPA’s compulsory reporting requirements that govern GHG production – implemented in January 2010 – are aimed at U.S. companies that release more than 25,000 tons per year of CO2 equivalent. Each Sierra Green house Gas flowmeter meets EPA requirements, and the technology provides an accurate, economical method to measure methane or natural gas burned and assess emission of carbon dioxide.

Sierra has extensive experience in producing gas flow meters for methane (CH4), as well asN20, SF6, HFCs and PFCs, which are also included in the EPA mandate.

In response to this new challenge facing our customers, Sierra has certified several metersideal for GHG measurement meeting all requirements defined by the new EPA rule. Look for our GHG Certified logo throughout the site to identify our GHG flow meters.In addition to new meters, Sierra can rapidly certify and recalibrate your existing Sierra meters sothat you can immediately meet the new requirements.

SteelMass™ Model 640S Insertion Mass Flow Meter

Landfill gas, the second largest source of CO2, is very humid, at low pressure (20 - 40 mBarg) and about 40-60°C (100F) when it leaves the landfill. The low pressure and dirty gas make differential pressure (DP) devices like orifice plates unsuitable, while the variable flows require a large turndown. Sierra’s SteelMass™ Model 640S Insertion Mass Flow Meter is ideal for this application since it boasts a 100:1 turndown, has no moving parts, and generates nominal pressure drop across the immersible sensor probe.

FlatTrak™ Model 780S In-line Mass Flow Meter with Flow Conditioning

Gas and electrical producers represent the next largest category ofCO2 emitters, and Sierra has long supplied its Flat Trak In-line Model 780S to these industries around the world. With its built-in Duel-Plate flow conditioning element, the 780S is an ideal meter for measuring gas flow in cramped or constrained piping environments where long straight pipe runs simply do not exist. The Model 780S is routinely used by gas and power plants to measure methane to compressors, pre-heaters, boilers and other process equipment.
