Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Measurement of density and viscosity of liquids at flows R.Q.MAMMADOV, V.A.ABBASOV, U.Q.MAMMADOV (E-mail: mulduz@mail.ru) The existing methods of measurement of density and viscosity of liquids directly at flow are analyzed and a new method of determination of these parameters is proposed. The proposed method is based on measurement of a fluid velocity for pendent and other various conditions of a ball and the forces operating on it. Various layouts of realizations of the method and the analysis of features of measurement are given. Key words: density, viscosity, liquid, ball, measuring tube, velocity, force.
