NRIPower Generation Research CenterProject Title :Design & Manufacturing of On-line ViscometerDepartment: Power Plant Operation StudiesProject Manager: M.R. ShahnazariM. MirtalaeiEmployer: Niroo Research InstituteProject Code: POPBT04Project Staff: K. Sadeghi, M.S. Aghighi, K. Gharali, G. Gandomnezhad, H.R.KhalesiSummary:A Couette-type viscometer was designed and manufactured to measure viscosity ofNewtonian fluids such as heavy oils. The primary goal was to design a viscometer tocontrol the viscosity of heavy oils in power plants. With a single pair of cylinders, and astrain gauge torque meter (0.12 Nm); viscosities between 5 to 2000 mPa.s can bemeasured. The electronic signals are handled and controlled by a controller that cansave the last 300 data and transfer them to computer.Calibration performed usingSAE10, SAE40, ISO32, and ISO46 Oils. The viscometer is installed in ShahidMontazeri power plant.31
