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.

Benefits

• Integrated real-time methane fraction measurement

• Optimized for low pressure gas – specialised sensor design

• No additional pressure loss – full bore design

• Process transparency – diagnostic capability

• Convenient device wiring – separate connection compartment

• Safe operation – no need to open the device due to display with touch control, background lighting

• Automatic recovery of data for servicing

Field of application

• The measuring principle is unaffected by gas composition

• Inline flowmeter designed for wet biogas, digester gas and landfill gas under fluctuating process conditions.
