color:#1F497D'>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.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>- I found one reference described at the biogas wiki about
‘upside down barrel’ method (and useful excel sheet!). <o:p></o:p></span></p>

offering with Qmax 4 m3/h) <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-GB style='font-size:11.0pt;font-family:"Calibri","sans-serif";

(Would special arrangement be needed e.g. pressure regulators?)<o:p></o:p></span></p>
