Prosonic Flow B200

The biogas market is booming. No wonder, as the gas obtained from fermentation of energy crops, organic waste, liquid manure, sewage sludge or leftover plant materials can be used in a variety of beneficial ways – including fueling vehicles or generating heat and electricity in combined heat and power plants.

For biogas plants to work properly, various process parameters have to be monitored around the clock: gas composition, pressure, temperature, and above all the produced gas quantity. Prosonic Flow B 200 is an industry-optimized ultrasonic flowmeter that measures the volume flow of biogas, landfill or digester gas reliably and with high accuracy, even under greatly fluctuating operating conditions.

Proline: Simply Clever
Demands made on process monitoring are becoming more complex and the need for maximum product quality is continually increasing. This is why Endress+Hauser continues to offer flow measuring technology that provides industry-optimized solutions for future requirements.

The new generation of our Proline flowmeters is based on a uniform device concept. For you, this means time and cost savings, as well as maximum safety over the entire life cycle of your plant.
