Flow rate at the landfill site’s wells and the collecting pipes leading to the combined heat and power plant
Gas wells, collecting pipes
Usually in each well from 0.2 m/s – 2 m/s or 30 m/s at the collecting pipe
Up to ATEX zone 1
Safe, fast measurement under all weather conditions (outside)
Data can be logged in a handheld unit and read later
Our handheld unit can be used with different flow sensors as well as other analog sensors
Mobile flow measuring in ATEX zone 1 with a handheld unit to analyse and save measuring data. To further increase accuracy the sensors can be calibrated with real gas. Alternatively you can use a transformation curve. Several of those curves can be stored in the handheld unit for different gases.
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).
Methane is one of the most significant greenhouse gases. Unless it’s caught it will continue to push global warming forward. That’s why its emissions have been successfully reduced. At the same time recording methane gas in landfills has been improved. The resulting methane is collected in wells and routed to the power generation. Due to the different compositions in a landfill and the continuously decreasing methane production all processes must be monitored.
