Abstract
A method of measurement of mass flow rates of multicomponent systems comprises directing gamma radiation from a collimated source onto extended scattering means irradiating the flowing medium with single-scattered gamma photons, detecting scattered photons with wide angle photon energy detectors and computing the flow rates from the component velocities and densities.
Claims2
A method of measurement of mass flow rates and reconstruction of time-averaged cross-sectional distribution of components of a multi-component flow system comprising:
- directing gamma radiation from a collimated source onto extended scattering means,
- irradiating substantially the entire flowing medium with single-scattered gamma radiation photons scattered by said scattering means,
- detecting scattered gamma photons with wide angle photon energy detectors separated by a predetermined distance,
- determining density and component velocities,
- computing component mass flow rates from the respective density and velocity and
- providing an image of flow cross-sectional density distribution.
