  • Patent number: 7911591
    Abstract: An L2F velocimeter comprises a probe for insertion into a fluid, the probe having an open area therein to allow the fluid to pass through. The probe comprises an illumination system to direct a pair of light beams, separated by a distance, through the open area, and a collection system to collect forward scattered light scattered from particles in the fluid. The collection system has an optical axis in common with the illumination system. The velocimeter further comprises an electro optical assembly connected to the probe to provide light to the illumination system, to receive light collected from the collection system, to measure a lapse time in fluctuations of the forward scattered light created by particles passing through the pair of light beams and to calculate the velocity of the fluid based on the lapse time and the separation distance.

  • Patent number: 7609368
    Abstract: A method for measuring the velocity of a multiphase fluid flowing in a pipe. The method comprises directing at least two collimated beams of light from an illuminator through the multiphase fluid by transparent portions of the pipe. The at least two collimated beams are spaced apart in a direction of flow of the multiphase fluid by a predetermined distance. The method also includes detecting scattered, deflected and attenuated light with at least two photodetectors to produce at least two signals. The at least two photodetectors are associated with the at least two collimated beams. The method also includes calculating a cross-correlation function between the at least two signals to determine a time delay between the signals and calculating the average velocity of the multiphase fluid by taking the ratio of the predetermined distance to the time delay.

  • Patent number: 7466399
    Abstract: The invention provides an optical flow meter for measuring fluid flow through a pipe which obviates the need for the flow to be seeded with foreign particles. The meter comprises a fiber optic Sagnac interferometer with optical path crossing the flowing fluid. The interferometer measures velocity of the fluid by measuring the phase difference between the two beams propagating in the optical path in opposite directions. Light, which is deflected by the fluid, is collected by optical means at both sides of the optical path for calculation, the scintillating statistics and compensation for light intensity.

  • Patent number: 7265832
    Abstract: An optical system design for measuring the velocity of fluids flowing through pipes or other conduits is disclosed. The optical system is comprised of a means for delivering two beams through a window in the wall of the pipe, focused to two points aligned along an axis of the pipe and separated by a known distance, and means for detecting light that is scattered by particles carried in the fluid stream through a second window, that is disposed on the opposite side of the pipe. By measuring the time delay between detected signals, the velocity of the fluid can be determined. The delivered light beams are focused in a shallow cone of light and are blocked by an obstruction disposed behind the second window. The scattered light passes through an aperture behind the second window that surrounds the obscuration, and is focused on to a detector surface.
