Abstract: Disclosed is a downhole tool comprising a fast hybrid telemetry module, and electronics module, and an acoustic flow meter tool module. Suitably, the fast hybrid telemetry module, the electronics module, and the acoustic flow meter tool module are assembled in series. Initially, the acoustic flow meter tool module is preferably provided for regular measurement of fluid temperature, fluid velocity, and fluid density in downhole oilfield production applications. Preferably, the electronics module is provided for data processing and self-compensation of the acoustic flow meter tool module (i.e., automated adjustment of acoustic wave energy and signal conditioning settings to perform flow rate measurements in a wide range of well bore conditions). Finally, the fast hybrid telemetry module is configured for bidirectional data transmission between the downhole tool and a surface data acquisition and monitoring station.
