Abstract

The invention provides a floating ball vortex street reflection type optical fiber flow sensor and a flow detection method thereof. The sensor has advantages of being small in structure, high in accuracy and reliability, high in adaptability and interchangeability and the like. The sensor is suitable for various fluid flow detection occasions. A vortex generator and a photoelectric sensing principle are combined to be applied to the field of flow detection. An output signal is processed by photoelectric conversion and signal processing calculation and then the output value is changes exponentially. Compared with the traditional power measurement mode, the provided flow detection method enables the detection sensitivity to be obviously improved and has the important practical application value. The sensor plays a great role in promoting the design and popularization of a novel flow sensor and belongs to the flow detection field.
