Many municipal sewage plants apply the activated sludge process where sludge aeration air is being pumped into aeration basins, speeding up the degradation process. To increase the plant’s energy efficiency flow velocity should be measured in order to calculate (mass) flow rate.

Portable or fixed measuring of landfill gas in single wells or at the gas well’s collecting pipe leading to the combined heat and power plant.

Anaerobic landfill gas is generated after attrition of the enclosed oxygen. Biomass stored in landfill waste is metabolised in a multi-stage degradation process resulting in mostly methane (CH4) and carbon dioxide (CO2).

Technical ventilation of rooms / monitoring ventilation systems for ex applications or for rooms with hazardous materials: battery production, mining, tunnels, laboratory, computer and clean rooms…

How can we explain something that’s invisible? That’s a problem everyone who works with gas flows in pipelines faces. How does flow behave after an elbow? What effect does a flow-rectifier have and what flow velocity occurs at different points of the cross-section?

Quenching is an important step in heat treatment of metallic materials like motoric components, machines or gears to target certain hardness grades and hardening depths in the material. Usually quenching happens through immersion in a quenching basin.
