Use of RFIDs to measure flow-rates of materials flowing through piping |
摘要 |
Material passing through a piping is laced with Radio Frequency Identification (RFID) tags. As the RFID tags pass an RFID sensor, which is either adjacent to or within the piping, a flow-rate of the material is determined by counting the rate at which the RFID tags pass the RFID sensor.
