Description

The invention relates to measuring equipment, in particular to viscosity controllers, and can be used to increase the efficiency and expand the scope of application of the device for rapid diagnosis of liquids.

An object of the invention is to increase the accuracy of the viscosity assessment of a test fluid.

The goal is achieved in that the upper part of the device is provided with two hollow necks, the cross-sectional areas of which are less than the cross-sectional area of the upper part of the device; the volume of the upper part of the device between the necks is less than the volume of the internal cavity about the lower part of the device; the ratio of the cross-sectional areas of the upper part of the device and necks is equal to the specified ratio of the immersion speeds of the device.

In FIG. 1 shows a device. The device comprises a cylindrical housing 1 with a throttle 2 installed therein from the side of the lower end, provided with

coaxially with the device, capillary 3. In the lower part of the device there is a cavity 4, the inner diameter of which is equal to the outer diameter of the upper part of the device. - - - g

On the upper cylindrical part of the device from the outside there are made necks 5, 6, the first of which corresponds to. device immersion lines at the initial moment, and second immersion lines to the end of the control process.

The operation of the device is as follows. . .

The device about the vertical position is immersed in the test fluid, pre-closing the hole in the upper part of the device. After immersion, the hole is opened. The test liquid enters the internal cavity 4 of the device through capillary 3 of throttle 2. When the immersion line reaches neck 5, the stopwatch is started, neck 6 is stopped, and the device is removed from the test liquid. Depending on diving time and taking into account

the previously measured temperature of the test liquid, its viscosity value is estimated. The speeds of movement of the immersion line relative to the device are shown in FIG. 2.

Obviously, such a device can be used under various conditions when the liquid is located in a beaker, bucket, barrel, tank, etc.
