title: A biogas meter with adjustable resolution and minimal back-pressure.
abstract: A new biogas meter was developed to satisfy the need for an adjustable resolution meter that has minimal back-pressure and wide flow rate capability. The new meter had three main components; a timed bellows pump that delivered fixed volumes, a pressure sensor, and a data logger. The meter was built from off-the-shelf components and was thus easy to build and cost effective. The meter also proved to be accurate, precise, sensitive, and simple to calibrate.
