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).

Controlling the degassed O2 content with the OXYTRANS TR Sensor in the vapour can reduce the steam loss in a boiler up to 95%

• Optical technology; no electrolyte and membrane changes
• Short response time and excellent long-term stability
• Ideally suited for high temperature applications

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
