FLUID MEASUREMENT DEVICE, FLUID MEASUREMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide a fluid measurement device and the like which minutely can measure a flow rate of fluid. SOLUTION: The fluid measurement device (10) is designed by comprising a generator-side detector (30) which detects a parameter indicating an operation state of the fluid generator (20) and varying according to the generation state of the fluid, a duct-side detector (40) arranged on the way of a duct (22) through which any fluid including the fluid generated by the fluid generator passes to detect the parameter regarding the fluid passing in the duct which vary according to the operation state of the fluid generator, and an operation part (50) for computing a flow rate of the fluid from time deviation between a variation in parameter detected by the generator-side detector and a variation in parameter detected by the duct-side detector and also a length (L) along the duct from the detected position of the parameter on the fluid generator to the duct side detector.
