Abstract
A converting map for an area of a backward air-flow is set based on a relationship between an output and a flow-rate, which are obtained in an air flow in which pulsation including the backward air-flow is generated. The backward air-flow has a dynamic property. The converting map of the present disclosure has a conversion characteristic, which is close to a characteristic in the backward air-flow. Accordingly, it is not necessary to correct the converting map by complicated processes and thereby accuracy of measurement for the area of the backward air-flow is increased.
