抄録

A simple structured flow speed sensor in which a polarization maintaining optical fiber is used as a Karman's vortex generator and also a vortex frequency sensor had been proposed. For measuring ocean current velocity, a double fine type sensor mount was designed and investigated in detail experimentally.Even if the experimental results showed its essential effectiveness, several problems were also found out. <br>A conduit type sensor mount has newly been proposed for solving these problems. A sensor for this mount has been constructed by using a 16φ circular pipe. Experimental results of the sensor shows a wide range agreement between detected frequencies vs, measured flow speeds and the expected frequencies with Roshko's equation. And the minimum detectable flow speed of 0.27m/s is obtained.
