摘要：An air flow measurement device measures a flow amount of air. A flow sensor isconfigured to output a voltage value corresponding to a given flow amount of the air. Atemperature sensor is configured to output temperature of the air. A correction

coefficient memory portion is configured to store a correction coefficient for correctingthe voltage value of the flow sensor to a corrected voltage value associated with thegiven flow amount based on a predetermined standard temperature. A relationshipbetween the voltage value of the flow sensor and the flow amount of the air changesbased on temperature of the air. A correction portion is configured to correct the outputvoltage value of the flow sensor to the corrected voltage value using the correctioncoefficient.
