Abstract
A new kind of practical fiber optic flow sensor system is studied in this paper. Combining the matured technology of conventional Rhodes flowmeter with advanced technology of fiber optic sensor, we proposed a practical scheme of hybrid fiber optic flow sensor system which remains the advantage of high accuracy of conventional Rhodes flowmeter, improves its characteristic in low speed and has large measuring range well over that the magneto-electric Rhodes flowmeter has. Thanks to the advantages of isolation, nonconduction and immune from electromagnetical interference, fiber optic flow sensor has steady output signal and can work without electricity on worksite. So it is used specifically in hazardous environments such as oil depot for oil and chemicals measuring. In this paper, the working principle of the flow sensor is introduced, the structure of the fiber optic Rhodes wheels rotary displacement probe is designed, and the signal-processing system is described. Finally the in-situ test of the system in the oil terminal of Zhanjiang Harbor in China is introduced.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
