摘要： A passive liquid flow monitoring system includes a monitoring device made of a liquid-soluble material in which coded transponders are releasably retained. The monitoring device may be deployed proximate a region of interest in a hydrocarbon-producing well. Characteristics of a liquid flow in the region of interest may be determined based upon detection of transponders that are released from the monitoring device when the monitoring device is exposed to the liquid flow.
