G'day Jos,
We found biogas was too corrosive to use a household meter for any length of time - you would have to get the H2S etc out and dry the gas. All the best, HOOROO Mr. Paul Harris, Room 202 Charles Hawker Building, Faculty of Sciences, The University of Adelaide, Waite Campus, PMB 1, Glen Osmond SA 5064 Ph : +61 8 8303 7880 Fax : +61 8 8303 4386 <mailto:[email protected]> mailto:[email protected] <http://www.adelaide.edu.au/directory/paul.harris> http://www.adelaide.edu.au/directory/paul.harris CRICOS Provider Number 00123M This email message is intended only for the addressee(s) and contains information that may be confidential and/or copyright.

From: [email protected] [mailto:[email protected]] On Behalf Of Jos van der Ent | Safi Sana Sent: Tuesday, 24 May 2011 10:43 PM To: For Discussion of Anaerobic Digestion Subject: [Digestion] Biogas volume measurements Hi All, I know there are more than one companies offering advanced measuring tools for gas(mass) flow meters. These are probably working fine for large scale systems, but I am wondering about methods for determining the biogas production of small scale systems (e.g. max 5 m3 biogas a day). The preference would go a simple meter, just like it can be done with water flow measurements. - I found one reference described at the biogas wiki about 'upside down barrel' method (and useful excel sheet!). - Also special biogas meters are sold on internet (e.g. Puxin is offering with Qmax 4 m3/h) - What would be against using a regular household flowmeter? (Would special arrangement be needed e.g. pressure regulators?) What accuracy would these methods have? Are there other options? What do they use in laboratories? What are the experiences with these methods? Thanks, Regards, Jos
