Abstract
A method and apparatus for measuring fluid flow by optically detecting the deflection of a tube extended transversely across a vessel normal to the direction of flow. A light source directs a beam of light axially into one end of the tube and the intensity of the beam is measured at the other end. Fluid flowing in the vessel tends to deflect the tube in the direction of flow thereby intercepting a portion of the beam and decreasing the intensity of light at the other end as a function of the rate of flow through the vessel.
