✦ Synopsis
A new design of a ¨ortex-shedding flowmeter with a ( ) fiber-optic Fabry᎐Perot interferometer FFPI as the sensing element is described here to measure the liquid flow ¨elocity in a pipe. The flow ¨elocity is determined by measuring the frequency at which the reflected optical power from the FFPI is modulated. Experimentally, a linear dependence of optical modulation frequency on flow ¨elocity is obser¨ed o¨er the range from 0.14 to 3.0 mrs, in good agreement with theoretical prediction.
