Falling ball viscometer

The falling ball viscometer is an instrument used in surface technology to measure the viscosity of liquids. It consists of a cylinder filled with the liquid to be tested and a ball that falls into the cylinder. The viscosity of the liquid influences the speed at which the ball sinks through the liquid.

In this method, the time it takes for the ball to travel certain distances in the cylinder is measured. The viscosity of the liquid can be calculated on the basis of these time measurements. The falling ball viscometer offers a fast and precise method for determining the viscosity of liquids over a wide range of temperatures and pressures.

In surface technology, the falling ball viscometer is often used to determine the viscosity of coating materials, varnishes, paints and other liquids that are to be applied to surfaces. By knowing the exact viscosity, manufacturers can determine the correct processing temperature, the appropriate application method and the optimum dilution for their products. This helps to improve the quality of the surface coating and make production processes more efficient.
