Fermentation processes are not always uniform. The operating conditions, which in some cases fluctuate greatly, result in different levels of methane content (CH4) in the biogas, which have to be monitored constantly. With the Prosonic Flow B 200, it is now possible – using precisely measured sound velocity and an integrated temperature sensor – to simultaneously measure the methane content directly in the pipe, without the need for additional devices. This is a worldwide one-of-a-kind feature and opens up completely new perspectives. Watch this video to learn more.
