摘要： A measurement unit includes a fluid inlet to let a fluid flow in, a fluid outlet to let the fluid flow out, and a single flow path connecting the fluid inlet with the fluid outlet. The measurement unit further includes a plurality of partition boards and a measuring instrument. The plurality of partition boards are disposed along a current of the fluid and between facing side surfaces of the flow path. The plurality of partition boards define M flow path segments (where M is an integer of 2 or greater) between the facing side surfaces. The measuring instrument measures a flow rate of the fluid flowing through N successively adjacent flow path segments (where N is an integer of 1 or greater and less than M).
