Mass flowmeters

January 28, 2010

Sierra introduced a line of mass flow meters Certified by Sierra for Green House Gas (GHG) reporting to the public. 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.

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.

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.
