Flow Sensing Apparatus and Flow Sensing Method using the same

摘要

The flow rate of the flow rate sensor and sensing method using the same are provided. The disclosed flow sensing device impeller rotationally driven by the raw water supplied from a number of bulbs arranged in a flow path, and is fastened to the impeller magnetic body having the shape of the N pole or structure in which the polarity of alternating the S pole rotates The magnetic force is separated to be placed on the body detects the polarity for detecting the polarity of the magnetic element sensor, and includes a control unit electrically connected to the polarity detection sensor, the control section change the polarity of the magnetic material from the polarity detecting sensor receives information on whether or not to be performed, characterized in that the determination as to whether the raw water is flowing in the flow channel. ; The invention flow whether or not the raw water in the flow path through the process of measuring the polarity change of the magnetic body by placing the polarity sensor to the magnetic material nearby is fixed to work on the impeller and the same axis that lies in the flow path By identifying the microcomputer is able to determine if the sensed flow rate of the raw water flowing into the flow path. ; Flow Detection, impeller, magnetic material, polarity, magnetic, microcomputer
