Abstract
A fluid measurement system includes a first sensor and a second sensor disposed on a same pipe and spaced apart from each other by a predetermined distance; and a measurement controller configured to calculate a flow velocity of a fluid flowing through the pipe based on first output that is output from the first sensor and second output that is output from the second sensor. The measurement controller performs a process including (a) comparing the first output and the second output in a first period of time so as to repeatedly calculate a first time difference between the first output and the second output while shifting the first period of time, (b) calculating a second time difference based on a frequency of occurrence of a plurality of first time differences each calculated in the first period of time, and (c) calculating the flow velocity based on the second time difference.
