Application
Flue gas type Air, flue gas, non flammable process gas
Flue gas temperature Above dew point,
-20 … 450 °C (-4 … 842 °F) standard, other on request
Flue gas dust concentration 0 … 30 mg/m3, type 1 (24x22mm) without backpurge
0 … 100 mg/m3, type 2 (54x50mm) without backpurge
0 … 150 mg/m3, type 3 (100x90mm) without backpurge
Inner duct pressure (relative to ambient pressure) -50 … +50 hPa standard, other on request
Flue gas relative humidity 0 … 95 % RH, non-condensing
Flue gas flow velocity 3 … 50 m/s
Stack/duct inner diameter 0.5 … 10 m (1.6 … 32.8 ft)
Measuring principle Measurement of ram pressure / differential pressure with a dual-chamber-probe
Measuring principle description The probe has two separate chambers between which the flow builds up a differential pressure. The evaluation unit determines the gas velocity and the volume flow (norm conditions or standard conditions) from the differential pressure, taking into account gas temperature and gas pressure
