Wang Bo Mo De ju (College of Information Science and Technology, Beijing University of Chemical Technology, Beijing 100029, China)
Based on the advantage of the wide foreground of an optical sensor, a kind of new type flowmeter - an optical fiber flowmeter which combined optical fiber technology with the traditional vortex flow measurement was designed. The measuring principle of the flowmeter, the principle of the vortex and the formulae of the optical fiber loss coefficient were presented. The improved structure of the sensor and the designs of the software and hardware were introduced. The principle schematics of amplification, filter, regulation circuit and flow chart were given. At last, based on the experiments data, the experimental results and the conclusion were discussed.
