Abstract

The gas flow inlets (41, 43, 45) are connected to a common chamber (47) which has a port (49) connected to a sensor (48) which measures the velocity of the gas exiting through this port by measuring the cooling effect of this gas flow. The sensor comprises an NTC (Negative Temperature Coefficient) component which is exposed to the flow of gas through the exit port and which has a resistivity that depends on the flow velocity. - The flow inlets extend transverse to the length axis for the flow channel (2) in which the device (40) is located.
