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 (14a or 14b) than on the other (14a and 14b), 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 the gas rate sensor output signal, using and updatable offset value to account for the instantaneous temperature change in the gas rate sensor.
