Methane (CH4) is a powerful greenhouse gas found in small quantities in the atmosphere. Methane is the simplest hydrocarbon, consisting of one carbon atom and four hydrogen atoms.
Methane remains in the atmosphere for over ten years and accounts for approximately 1/3 of all methane emissions in landfills (landfills are the largest human-related source of methane in the U.S.). It is 21 times more effective at trapping atmospheric heat than carbon dioxide and is of growing environmental concern. As a result, it is a major focus of greenhouse gas reduction initiatives. Furthermore, methane is a primary constituent of natural gas and is an important energy source. Efforts to utilize methane emissions can provide energy, as well as economic and environmental benefits.
Sage thermal mass flow meters help quantify captured emissions from landfills, including biogas and digester gas. Carbon Offset projects use these meters for measuring mass flow rate, even when the flow is low. The Sage TMFM provides a very easy way to conduct the required periodic calibration field checks using its unique In-Situ Calibration procedure.
