Sehnellvlskosiiaeter

The invention relates to a Sehnellviskoslffieter star the deviation of the viscosity of a liquid from target values.

Various devices for determining the viscosity of liquids are already known. "These devices built * with which, in general, the absolute value of the viscosity bestlsimt wlrdg are relatively complicated addition, the au measured liquid and must be gebrsoht uf a vorbestismnt © temperature.

With one of these devices, the Auslmifviäkosimeterj, the time is determined in which a small amount of the liquid to be measured flows out through a pipe. For this purpose, the liquid to be measured must first be brought to a predetermined temperature. uevaen ₉ % m then, from the time required for the outflow, infer the absolute value of the viscosity ssa «

In the case of a second device, "the capillary viscosi & eter" is used the time determines * that a measured volume of oil needs * to flow through a defined capillary in laminar flow ssu '. Here, too, the liquid to be measured must have a predetermined temperature own «in order to be able to calculate the absolute value of the viscosity from the measured tent.

In a third device, the "ball allvlskosiitieuePj," the falling side of a ball is coated with the oil to be seeded in a drill is extraordinarily sehnieslg

In a fourth device, a rotary viscometer, test specimens are allowed to rotate at a constant speed in the liquid to be measured, and the viscosity which is then determined is determined.

In practice, however, the absolute value of the viscosity of a liquid is very often not required at all ₅ ; instead, it is sufficient to know the extent to which the viscosity of this liquid deviates from the specified target values.This is the case, for example, in car repair shops where the Abs * eleh * mg © n the viscosity of the motor oil feiif certain errors in the Ifotov can be inferred «

Bs is therefore the object of the invention to provide a viscometer stu ship έτι "that is as simple as possible and with the aid of country robust as quickly as possible the differences d can be determined setpoints © r viscosity of a liquid.

This task is isair determination with a high speed iriskpsimeter the deviation of the viscosity of a liquid from: target values.

solved by the fact that at the same time. on with liquid from set point filled * a 'body. containing pipe is provided " next to the one a similar falling body. containing Eohr the same
