Abstract: A flow meter for determining the flow rate of a fluid through a conduit, including an upper body having an inlet chamber, an acoustic channel, an outlet chamber, a sound wave generator, and a sound wave receiver. The inlet chamber, acoustic channel, and outlet chamber are fluidly connected together and are oriented so as to create a symmetrical fluid pathway through the inlet chamber, the acoustic channel the outlet chamber. The sound wave generator and the sound wave receiver are aligned along a longitudinal axis of the acoustic channel and the sound wave generator is creates a sound wave that moves along the longitudinal axis of the acoustic channel as fluid flows through the acoustic chamber. The receiver detects that sound wave that has moved through the acoustic channel and such information is used to determine the flow rate of the fluid through the flow meter.

Abstract: A flow meter for determining the flow rate of a fluid through a conduit, including an upper body having an inlet chamber, an acoustic channel, an outlet chamber, a sound wave generator, and a sound wave receiver. The inlet chamber, acoustic channel, and outlet chamber are fluidly connected together. The acoustic channel is a non-linear pathway that is symmetrically dimensioned. The sound wave generator is configured to create a sound wave that moves along the liquid pathway formed by the acoustic channel. The receiver detects that sound wave that has moved through the acoustic channel and such information is used to determine the flow rate of the fluid through the flow meter.
