Abstract (en)
[origin: US6216543B1] A flow monitoring method and device including introducing at at least a point in a pipeline at least one detectable body carried by the flow of liquid. A stationary detector for detecting the passage of the detectable body, wherein, the detectable body contains an electronic chip associated with an antenna, for being detected by electromagnetic method. The antenna at least transmits a signal to and receives a signal from the stationary detector. An interceptor for intercepting the detectable body at at least a point in the pipeline.
