  • Cyclonic flow meters and method of using same
    Patent number: 5905200
    Abstract: Detection of the flow of a fluid, and also measurement of the flow of a fluid, is provided by feeding the fluid flow through a cylindrical chamber to form a cyclonic circulation of the fluid in the chamber. A movable member is moved by the fluid flow. As one example a ball rotates around the inside of the chamber and the passage of the ball detected, at a particular position. An alternative is an annular member also rotated. There can be an optical detection or electronic detection. Output signal can be generated by the movement. Such signals can be processed to give flow rates. The chamber is positioned in a by-pass flow line, with the flow rate of the by-pass related to the total flow.
