Summary:To disclose one example of a flow rate detection device.SOLUTION: A flow rate detection device includes: temperature sensors 11A, 11B for detecting the temperature rise degree of water flowing through a casing 2B when a pump 2 is operated; and an arithmetic device 12 for determining the discharge flow rate by utilizing relationship between the detected rise temperature detected by the temperature sensors 11A, 11B, and the previously stored relationship and the flow rate. As a result, the amount of water delivered by the pump 2 can be detected using the correlation between the discharge flow rate of the pump 2 and the degree of increase in temperature of water.SELECTED DRAWING: Figure 1 【課題】 流量検出装置の一例を開示する。【解決手段】 ポンプ2が稼働しているときにケーシング2B内を流通する水の温度上昇度を検出する温度センサ11A、11Bと、温度センサ11A、11Bにより検出された検出上昇温度、及び予め記憶されている上昇温度と流量との関係を利用して吐出し流量を決定する演算装置12とを備える。これにより、ポンプ2の吐出し流量と水の温度上昇度との間の相関関係を利用してポンプ2の送水量を検出できる。【選択図】 図1
