December 17, 2009 — Sierra Instruments introduced a line of mass flow meters for Green House Gas (GHG) reporting. All Sierra GHG meters now conform to the new EPA rule (40 CFR Part 98), which mandates that as of January 2, 2010, companies in the United States that emit more than 25,000 tons/year of CO2 equivalent must report GHG emissions. It is estimated that approximately 10,000 of the country’s largest businesses will be affected. Sierra’s GHG Certified mass flow meters provide an economical way to totalize methane or natural gas burned, enabling the calculation of CO2 equivalent emissions. Sierra has extensive experience in producing highly accurate and repeatable mass flow meters for methane (CH4) as well as N20, SF6, HFC’s, PFC’s and CO2 as called out in the EPA mandate.
The three GHG Certified thermal mass flow meters the Boiler-Trak, Model 640S, and Model 780S. Sierra’s Boiler-Trak is a thermal mass flow meter designed for stationary combustion applications (commercial boilers, kilns and heaters), which are among the largest emitters of CO2. To date, over 15,000 units have been successfully installed. Sierra’s Model 640S has been optimized for landfill gas, the second largest source of CO2. Landfill gas is very humid, at low pressure (20-40 mBarg) and about 40°-60°C (100°F) when it leaves the landfill.
Given that the 640S has 100:1 turndown, no moving parts, and generates nominal pressure drop across the immersible sensor probe, it is ideal for this application. The Sierra Model 780S was designed for gas and electricity producers, the third largest category of CO2 emitters. This flow meter is routinely used by gas and power plants to measure methane to compressors, pre-heaters, boilers and other process equipment. “This is really our strong suit,” says Matthew J. Olin, President of Sierra.
“Our customers saw the environmental writing on the wall some time ago and we have been steadfastly pursuing both sustainable and profitable industry flow measurement solutions ever since. To make it easier for our customers facing this measurement challenge to find the meter they need, we’ve established a dedicated webpage www.sierrainstruments.com/greenhouse.html that features our three most popular GHG Certified mass flow meters.
We’ve also trained our team of flow application and service engineers in the EPA Greenhouse Gas reporting rule so they can answer customer questions.”
