title: Compact automated displacement gas metering system for measurement of low gas rates from laboratory fermentors.
abstract: An automated metering system was developed for measuring biogas production from laboratory scale biogas digestors. The gas metering system is based on the principle of liquid displacement with a 100-mL reversible cycle and registration. The gas meter is made entirely of plastic and rubber materials resistant to the corrosive components of biogas (e.g., H(2)S) and requires a 12 to 15 VDC power supply.
