    The design and construction of a descending sphere viscometer was carried out to be used as support material for the studies of the fluid laboratory of the Mechanics Degree of the Technical University of Ambato so that it is easy to operate and maintain. The project was carried out based on research on viscosity and how to measure it, information was consulted on the types of viscometers most used by industries; The ISO12058-1 standard was reviewed, which indicates the inclination of the tube, the recommended size of the spheres and the distance of the sensors. After having obtained all the necessary information, we continued with the design of the device, then acquired the necessary materials for its installation. construction such as the Liebig tube, servomotor, steel spheres, sensors and the microcontroller, essential devices in the operation of the viscometer, once built, the operation of the device was programmed, which is managed from the control box; It was verified that the device did not have cracks through which the fluid could escape. Initial tests were carried out with distilled water with which the operation of the sensors was also verified, whose error cannot exceed 2 percent. Finally, 20w50 oil was experimented at 40 degrees Celsius using SAE 40 oil at 40 degrees Celsius as calibration fluid. As a result, it was proven that the device performs its main function of measuring the fall time of the sphere, and then using the Stokes equation to determine the viscosity of the measured fluid.
