Volumetric gas meter for laboratory-scale anaerobic bioreactors

This paper proposes a volumetric gas meter, on-line, based on the liquid displacement principle. The proposed measuring device is the capacity to measure volumetric gas in a range from 1 mL to 1000 mL, from a laboratory-scale biogas reactor. As application, the meter is used in order to obtain the biogas production data file of a laboratory-scale Upflow Anaerobic Sludge Blanket (UASB) reactor.
