AN IN-LINE DENSITY AND VISCOSITY SENSOR
In-line density and viscosity sensors for liquids are developed to utilize measurements of differential pressure across a nozzle and a coiled capillary tube respectively, with known flowrates through each provided by a flow generator. Theory and principles of operation and instructions for calibration and use of the sensors are discussed, along with design consideration for the sensors and associated equipment. A calibration of the sensors demonstrated that viscosity and density each could be measured with a computed standard deviation of one percent. Viscosity was varied over the range of about 1 to 11 centistokes whereas density of the fluids used was near 0.8 g per cc. Application of similarity considerations is used to make the results applicable to other liquid densities.
