Automatic removal of gas overestimation
Methane gas overestimation arises after flushing the system with an inert gas such as nitrogen. Consequently, carbon dioxide in the newly formed biogas is mistakenly counted as methane gas. This can lead, in some cases, to an overestimation of methane gas production by as much as 20–30%, and even more depending on the volume of the headspace. The AMPTS® II calculates and removes this overestimation, providing for more accurate and reliable data on methane gas production.
