Sierra Mass Flowmeters Are GHG Certified
Sierra Instruments has introduced a line of mass flowmeters certified by Sierra for greenhouse gas (GHG) reporting. The company said that all Sierra GHG meters now conform to the new EPA rule (40 CFR Part 98), which mandates that as of 2 January 2010, companies in the US that emit more than 25,000 tons/year of CO2 equivalent must report GHG emissions. Sierra claimed its GHG certified mass flowmeters provide an economical way to totalise methane or natural gas burned, enabling the calculation of CO2-equivalent emissions. Sierra has experience in producing accurate and repeatable mass flowmeters for methane (CH4) as well as N20, SF6, HFCs, PFCs and CO2. The three GHG certified thermal mass flowmeters are the Boiler-Trak, model 640S and model 780S. Sierra Boiler-Trak is a thermal mass flowmeter designed for stationary combustion applications (commercial boilers, kilns and heaters), which are among the largest emitters of CO2. Sierra model 640S has been optimised for landfill gas, the ...
