Abstract
This fluid measuring device is provided with: an irradiation unit that irradiates a fluid with light; a light receiving unit that receives light scattered by the fluid; a detecting unit that detects a backflow of the fluid on the basis of a light reception signal from the light receiving unit; and a calculating unit that calculates, on the basis of the detection result by the detection unit and the light reception signal from the light receiving unit, estimated fluid information indicating the flow rate or flow speed of the fluid. Accordingly, even when a backflow of the fluid temporarily occurs, the flow speed of the fluid can be precisely measured.
