Abstract

A optical fiber flowmeter based on the correlation technique is developed.According to the small size of optical fiber probe and the advantage of correlation processing,the mathematical model established for the optical fiber correlation flow measuring system can be simplified reasonably by means of "frozen pattern"hypothesis,and a simple,convenient expression can be obtained. In the system,the signal gained from the transmitting probe is transferred through the optical fiber,and then processed by pre-amplifier,high speed recorder,finally,the signal is correlated by microprocessor ,and the velocity can be obtained from the delay time.
