In-line viscosity measurement using pressure and flow rate sensors
A novel method for determining fluid viscosity utilizing in-line pressure and flow rate sensors, with calibration for non-Newtonian and non-laminar flows. Offers real-time process analysis through automated correction software, enhancing control in industrial applications.
Overview
Eric Brown Labs LLC presents an innovative technique for in-line viscosity measurement, employing pressure and flow rate sensors to determine the viscosity of fluids directly in industrial processes. This method leverages a calibration procedure using known viscosity standards to derive a coefficient that relates pressure and flow rate to viscosity. The technique is particularly advantageous for processes involving molten plastics and other non-Newtonian fluids, where traditional viscosity measurement methods may fall short. This solution provides real-time process analysis and automatic correction for non-linear flow behaviors, offering enhanced control and efficiency in manufacturing settings.
