Application
Anaerobic degradation processes happen in the digestion tower during wastewater treatment in a sewage plant, causing biogas (also sewage or fermentation gas) to arise, which mainly consists of methane and carbon dioxide.
Exact measuring of biogas quantity is one oft he most challenging applications in flow measuring technology. Biogas is very moist, tends to condensate and is particle-laden. Its composition varies and is quite aggressive. Combined with air it can turn into explosive mixtures which is why it’s important to take according safety measures. Applied instruments have to be certified for the defined ex zone
Fermentation gas is measured directly at the digestion tower’s exit and on the other side before the combined heat and power plant. Flow rate towards the flare is also partly measured.
Your advantage:
Safe
Safe measurements even in hazardous areas
Economical
Once installed, the sensor hardly needs any maintenance
Robust
Our vortex sensor is especially suited for condensate-laden fermentation gas that can also be particle-laden
