METHOD AND DEVICE FOR MEASURING DENSITY OF FLUID Russian patent published in 2007 - IPC G01N9/24 

FIELD: measuring technique.

SUBSTANCE: device comprises pipe for flowing the fluid, source of photons mounted at one of the ends of the pipe, and detector of photons for receiving the photons passing through the pipe in the longitudinal direction. The pipe has the first and second axially aligned straight sections mounted from the opposite sides of the source of photons. Each measurement section receives appropriate photon from a pair. The detectors mounted at the other ends of the measurement sections receive photons from the pairs. The density of the fluid is judged by the number of coincident photons.

EFFECT: enhanced precision.
