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.
