Flow Sensing Apparatus and Flow Sensing Method using the same

摘要

The flow rate sensing device and the flow rate detection method using the same are provided. The disclosed flow sensing device is magnetic body having a shape of a structure in which the polarity of the N pole or S pole are alternately repeated as the impeller rotationally driven by the raw water supplied from a number of bulbs arranged in a flow path, it is fastened to the impeller rotation , are arranged spaced apart on said magnetic body includes a microcomputer receiving transmit information about whether or not to change the polarity of the magnetic body from the polarity detecting sensor for detecting the polarity of the magnetic body, and the polarity detection sensor, the microcomputer is the polar atmosphere maintaining only its own standby power of the microcomputer with no power supplied to the sensor mode, medium mode, supplying power for the resuscitation time set up in the microcomputer by the polarity detection sensor, and the polarity change of the magnetic body in the intermediate mode, through the continuing power supply to the polarity detection processor if the detected and a measurement mode for detecting the flow rate of the flowing raw water in the flow path, the microprocessor is the intermediate said standby until detecting a polarity change of the magnetic body It characterized in that the continuously switch between the modes. ; The present invention relates to a flow sensing device by allowing variation cycle microcomputer is usually an intermediate mode for sensing the polarity by supplying the standby mode and power to the polarity detection sensor to maintain the minimum standby power state and non-constant exchange between the modes it is possible to promote the efficient use of the power supplied. ; Flow sensing, impellers, magnetic material, polarity, magnetic, microcomputer, standby mode, intermediate mode, measurement mode, resuscitation time, wakeup
