Abstract
A fluid measurement device includes sensor elements that are arranged around a pipe in which a fluid containing a scatterer flows and include each of a light source, a light receiver, and a partition structure for shading between the light source and the light receiver, a signal processor that processes the signals obtained from the light that has been received and photoelectrically converted by the light receivers, and a calculator that calculates at least one of a flow velocity and a flow rate using the signals processed by the signal process unit. The light source and the light receiver in each of the sensor elements are arranged in proximity along the pipe axis direction of the pipe so as to have a reverse positional relationship to the light source and the light receiver in the adjacent sensor elements.
