Abstract

The optical fiber flow sensors for automatic measurement in oil industry are considered excellent sensing components owing to the advantages of the immunity to electromagnetic interference and intrinsic safety telemetry. But there are not many commercially fiber optic flow sensors because of the high cost and immature measuring technology. Based on the advanced technology of optical fiber magneto-optic sensor and the matured technology of turbine flow sensor, a new kind of optical fiber mass flowmeter is studied to meet a fast growing demand for measuring flow in mass units instead of volumetric units. It not only keeps on the advantages of the turbine flowmeter, such as high accuracy, large measuring range, but also reduces the effect of electromagnetic noise from the environment, improves the response characteristics in the low frequency. In this paper, the basic principles of the optical fiber mass flowmeter is presented. The design of the optical fiber magneto-optic sensor is studied in detail and the effective method for signal processing is also discussed. Experimental results show that the optical fiber magneto-optic sensor can respond to high frequency of up to 1 KHz and the measurement accuracy of rotational velocity is about 0.1%.
