A biogas meter with adjustable resolution and minimal back-pressure

Area of Science:

• Environmental Engineering
• Instrumentation and Measurement

Background:

• Biogas production requires accurate flow measurement for process optimization and efficiency.
• Existing biogas meters often lack adjustable resolution, sufficient flow rate range, or exhibit high back-pressure.

Purpose of the Study:

• To develop a novel biogas meter with adjustable resolution and wide flow rate capability.
• To create a cost-effective and easy-to-build biogas measurement instrument.

Main Methods:

• The biogas meter was constructed using off-the-shelf components.
• Key components include a timed bellows pump for fixed volume delivery, a pressure sensor, and a data logger.

Main Results:

• The developed meter demonstrated adjustable resolution and wide flow rate capability.
• Performance evaluations confirmed the meter's accuracy, precision, and sensitivity.
• The instrument proved to be simple to calibrate.

Conclusions:

• The new biogas meter effectively addresses the limitations of existing technologies.
• Its design offers a practical, accurate, and cost-efficient solution for biogas flow monitoring.
