APPARATUS TO SIMULTANEOUSLY MEASURE DENSITY AND VISCOSITY OF LIQUID

摘要

PURPOSE: A device for simultaneously measuring the density and viscosity of fluid is provided to facilitate maintenance and replacement as a sensor beam which is contained in the fluid has a structure detachable to a vibration generating unit. CONSTITUTION: A device(100) for simultaneously measuring the density and viscosity of fluid comprises a sensor beam(110), a vibration generating unit(120), and a vibration measuring unit(130). An end portion of the sensor beam partially contacts to the fluid. The sensor beam is formed into a cantilever type. The vibration generating unit generates a vibrating force which vibrates the sensor beam. The vibration measuring unit measures the vibration of the sensor beam. The density and viscosity of the fluid are simultaneously measured by measuring an interaction force between the sensor beam and fluid.
