Abstract
In order to reduce a flow rate error over the entire range of a sensor output value even when the relationship between the sensor output value and a flow rate value is poor in linearity, a flow rate sensor correction device includes: a sensitivity setting part adapted to set a sensitivity coefficient on the basis of an initial value and a sensitivity correction value and adjust the sensitivity of the flow rate sensor; a function calculation part adapted to calculate a corrected flow rate characteristic function on the basis of a function correction value, which is determined on the basis of the flow rate value, and a standard flow rate characteristic function; and a function modification part adapted to make a function storage part store, as a flow rate characteristic function, a final flow rate characteristic function based on the corrected flow rate characteristic.
