Abstract
A fluid measurement apparatus according to an embodiment includes an optical emitter capable of radiating light to an irradiation target including a fluid, an optical detector capable of receiving scattered light scattered by the fluid, and a controller that includes a generator configured to generate a frequency spectrum based on the scattered light and an estimation unit configured to estimate a flow state of the fluid, based on a characteristic component of the frequency spectrum. The controller causes the generator to generate a first frequency spectrum based on a measurement target fluid and a second frequency spectrum based on the fluid in a known flow state, and then causes the estimation unit to compare a characteristic component of the first spectrum and a characteristic component of the second frequency spectrum, whereby the controller can estimate a flow state of the measurement target fluid.
