Combustion air pipe

Combustion air flow and volume measurement

Process data

Measuring task:
Differential pressure measurement
Measuring point:
Measuring range up to:
30 mbar
Air and coal dust
Process temperature:
+200 … +400 °C
Process pressure:
0 … +1 bar
Special challenges:
Very small measuring ranges, high temperatures


To ensure an optimum combustion process in a coal-fired power plant, the amount of air flowing in the pipes leading to the furnace must be carefully monitored. A Venturi section of the air pipe is a defined constriction in which the pressure drops a few millibars proportional to flow rate. Differential pressure transmitter measures the pressure drop across the measuring section very accurately and calculates the air flow rate.
