ABSTRACT:
A method and apparatus for measuring fluid flow by placing two pressure sensors diametrically opposite each other in a flow line. The use of two sensors effectively cancels acoustic pressure fluctuations while preserving the local turbulent pressure fluctuations. The turbulent pressure fluctuations are proportional to the square of the flow rate of the fluid and are processed by the electrical circuit to derive a quantity proportional to the fluid flow rate.
