Abstract
Disclosed is a gas rate sensor system which provides an output signal representing an angular velocity of the gas rate sensor when the gas flows more on one of its thermal sensing elements than on the other due to the effect of the angular velocity on the gas flow. The gas rate sensor system can carry out an arithmetic operation for correction of gas rate sensor output signal by selectively using a preset value representing the change of the gas rate sensor output signal with temperature in the gas rate sensor.
