Title:
FLUID MEASUREMENT SYSTEM AND FLUID MEASUREMENT METHOD
Document Type and Number:
Japanese Patent JP2023173350
Kind Code:
A
Abstract:
To provide a fluid measurement system and fluid measurement method that can measure the flow velocity of a measurement fluid with high accuracy.SOLUTION: A fluid measurement system includes a first sensor and a second sensor disposed on the same pipe and spaced apart from each other by a predetermined distance, and a measurement controller that calculates the flow velocity of a fluid flowing through the pipe on the basis of first output that is output from the first sensor and second output that is output from the second sensor. The measurement controller performs the steps of: (a) comparing the first output and the second output in a first period so as to repeatedly calculate a first time difference between the first output and the second output while shifting the first period; (b) calculating a second time difference on the basis of frequency of occurrence of a plurality of first time differences each calculated in the first period included in a second period that is longer than the first period; and (c) calculating the flow velocity on the basis of the second time difference.SELECTED DRAWING: Figure 1
