Description

The Prosonic Flow B 200 has been specially developed for the biogas industry. It measures the volume flow of biogas, landfill or digester gas with high accuracy, even under greatly fluctuating operating conditions. In addition the Prosonic Flow B 200 offers in-situ methane content measurement. This unique feature enables continuous measurement of not only gas flow but also gas quality.
