    Abstract: Flow metering devices are one of the most important apparatus to measure/control fluid flows in pipelines, including industries such as chemical/petroleum plants, as well as residential/municipal facilities. In recent years, the systems have advanced into digital era with the development of science and technology. However, batteries and wired electricity are still the major operating power.
    In this proposed “Self-Powered Pipe Flow Metering System (SPPFM)”, the pipe flow drives the rotor of a generator to power the measuring unit itself. Thanks to the system, only small part of the flow power is converted into electric power to obsolete the replacement of batteries or to eliminate the lengthy electric supply wires all together.
    Major parameters including power needed and power generated under different flow rate are investigated. Based on the results of the experiments, feasibilities of the system are discussed. A commercial flow meter was used to calibrate this SPPFM system and the results of such a calibration are presented in the paper. A technique to achieve both goals using single generator hardware is explained. It was seen from the experiment that the SPPFM system would produce more electric power than the basic needs for an embedded digital measuring unit, leaving rooms for growing features such as wireless communication, graphic display and data storage.
