Measuring exhaust air, supply air and burner gas for thermal Post-Combustion
Thermal or thermal regenerative post-combustion is the process of cleaning industrial exhaust gases. Contaminated air, explosive process gases, flare and waste gases are lead to a combustion chamber and burned in temperatures between 700 °C and 1,200°C.The Höntzsch Vortex sensor with ATEX and SIL certification measure the flow rate of inflowing, solvent-containing exhaust air to manage the high energy consumption in combustion. They are robust (no moving parts) with longevity and minimal maintenance.
Measuring airflow in sterilizing tunnels in the Pharma industry
In sterilizing tunnels hot air flows through the so called HEPA-filter down into the heating zone. There, sterilizing hot air with a very low flow velocity is blown down to the glas containers and monitored with Hoentzsch Vane Wheel Flowsensors.
Measuring laminar flow in paint booths, clean rooms, semiconductor production
Flow velocity for process regulation for paint booth, clean rooms, semiconductor and filling and packaging applications.
Measuring sludge aeration in sewage plants
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.
Measuring landfill gas
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).
Measurements of air exchange in forced-ventilated rooms
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…
Visualising rotational flow of invisible gas
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?
Monitoring forced ventilation on LNG ships
Measuring air exchange in engine rooms on LNG (liquified natural gas) ships
Forced engine room ventilation of LNG ships is required to prevent the rise of dangerous atmospheres.
Polymer Vortex Flow Measurement for corrosive and caustic gases
Hoentzsch in Germany developed a new Polymer vortex sensor for highly aggressive gases in the chemical industry, petrochemistry, semiconductor industry, electroplating and applications with halogenated gases which do not allow metallic material. The only parts contacting the medium are the sensor body made of high-performance polymer, the transducer made of aluminium oxide ceramics and seals made of fluororubber.
Biogas & Sewage Gas Vortex Flow Measurement
Flow measurement of Biogas has faced huge problems due to high humidity, condensation, particles, varying compositions, aggressive and explosive media and marginally low air flow.
The Hoentzsch Vortex VA Flowmeter offers an accurate measurement solution for the Biogas environment:
- starting from very low gas flow velocity (0.4 m/s)
- measuring dynamics (turndown) 1:100
- largely insensitive to condensation and particle deposits
- almost no cleaning and servicing necessary
- accurate measurement with variable gas compositions
- low pressure drop, no moving parts
- SIL and Ex-proof certifications available
