Factors that are affected the influence of the measurement error of the refractive index n in the flowing liquid (change in its optical density and temperature) are established. A during the using a differential flow type refractometer for measuring n flowing fliquid on the error in measuring the refractive index is additionally influenced by the scattering of radiation in the cell transducer and the wedge-shaped glass of the cell. New design of a differential refractometer for investigation of the optical density influence of the flowing liquid on the measurement error n is developped. New results confirming the influence of changes in the optical density of the flowing liquid on the measuring error of the refractive index n are recived. Compensation technique of the changes influence a optical density on the measurement error n is offered.
