Filed: 2003-05-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide a flow velocity measuring method and device by a plaster columnar body for simultaneously detecting the distribution of flow direction and flow velocity.  <P>SOLUTION: The plaster columnar body 2 is vertically held for a fixed time period in a water flow 1 with plurally layered substantially horizontal stream surfaces. At each required point on an axis line of the columnar body 2, an average flow direction and flow velocity for a fixed time period of the stream surfaces passing such a point are detected as a direction orthogonal to a direction in which outer diameter abrasion of a cross-section of the columnar body 2 at such a point due to the relevant stream surfaces is maximum and as a flow velocity corresponding to the maximum value of the relevant outer diameter abrasion. The vertical distribution of flow directions and flow velocities are found from detection values at the plurality of required points. A self-supporting tool for removably holding the columnar body 2 in a prescribed attitude is fixed on the bottom of a waterway to quicken and facilitate the installation and disinstallation of the columnar body 2 when starting measurement and ending measurement.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
