Summary:The present invention has a heating unit that heats a fluid being measured, and a temperature detection unit that detects the temperature of the fluid being measured. The flow amount of the fluid being measured that flows through a main flow path is corrected on the basis of the tendency for a detection value obtained by the temperature detection unit to change over time. La présente invention comprend une unité de chauffage qui réchauffe un fluide soumis à une mesure, et une unité de détection de température qui détecte la température du fluide soumis à la mesure. La quantité d'écoulement du fluide soumis à la mesure qui s'écoule à travers un trajet d'écoulement principal est corrigée sur la base de la tendance d'une valeur de détection obtenue par l'unité de détection de température à varier dans le temps. 測定対象流体を加熱する加熱部と、測定対象流体の温度を検出する温度検出部と、温度検出部による検出値の時間経過に伴う変化傾向に基づいて、主流路を流れる測定対象流体の流量を補正する。
