KROHNE has successfully deployed its flowmeter solutions for many applications throughout the world to deal specifically with the growing demands for accurate biogas flow measurement in a wide and seasonally varying operational range. Here are two specific stories that highlight the applications’ challenges and the resulting benefits.

Anaerobic Digestion occurs in biodigesters and produces a fuel (biogas), removes Biochemical Oxygen Demand (BOD) from sewage, conserves nutrients (especially nitrogen compounds) and most importantly reduces pathogens. The biogas, in turn, can be used as a supplemental heat or power generation energy source. Depending on the influent, and the treatment facility’s size and design, the resulting biogas flowing conditions can vary greatly from season to season and from plant to plant.
