Abstract
This fluid evaluation device is provided with an irradiation unit for irradiating a fluid with light, a light reception unit for receiving scattered light from the fluid and outputting a light reception signal, and an estimation unit for estimating at least one from among flow rate and density by mapping input points, which are on a first plane defined by flow rate and frequency and are expressed by light amount information indicating the amount of scattered light included in the light reception signal and frequency information indicating a frequency for a beat signal resulting from the Doppler shifting of the light included in the light reception signal, onto a second plane defined by fluid flow rate and fluid density.
