FIELD: instrumentation.
SUBSTANCE: invention is intended for measuring multicomponent mixture stream coming out of well. Fluid stream consisting of the first component (oil) and the second component (water) is directed into the first pipeline (108) where it is divided into two streams using gravity. Using the second pipeline (110) connected with the first pipeline water is continuously sampled from the liquid flowing in the pipeline (108), and sample density is measured in the second pipeline using Coriolis flowmetre (116).
EFFECT: increasing measurement accuracy while reducing labor consumption.
