A data fi le can be edited with spreadsheet software.
See “16.5.2 Measured data fi le” located toward the end of the volume for the recording
format.
(2) Flow velocity distribution … Beneath VEL folder just beneath folder of site name
• Created flow velocity distribution data file name: Vel_date_hour.csv
A data fi le can be displayed using fl ow velocity distribution demonstrate function of PC
loader software.
See “16.5.3 Flow velocity distribution fi le” located toward the end of the volume for the
