Viscometers are largely divided into a drag flow type and a pressure-driven flow type.

The former refers to a form in which shear occurs between a stationary surface and a moving surface, such as a Couette device, and the latter refers to a form in which shear occurs due to a pressure difference between both ends of a tube.

In addition, the general capillary viscometer belongs to the latter pressure-driven flow type.

The capillary viscometer as described above is the first invented viscometer and is still the most widely used, due to inherent advantages such as the characteristics of the capillary viscometer, that is, simplicity, accuracy, similarity to actual flow, and the absence of a free surface.

In connection with such a technique, a capillary viscometer is disclosed in Korean Patent No. 353425, which is configured to store a measurement fluid and store a pressure difference generated by a height difference or an external force, as shown in FIG.

In addition, the cylinder of the present invention provides a cylindrical viscometer composed of a configuration in which one side of the outer cover provided on one side of the casing is opened to the upper side of the casing, the casing is provided with a pipe connected to one check valve. .

In addition, the casing of the present invention provides a cylindrical viscometer composed of a configuration in which the discharge hole is penetrated to discharge the fluid raised by the piston on one side thereof.

Subsequently, the check valve of the present invention provides a cylindrical viscometer which is installed to open at the pressure acting by the raised piston while the piston is always in close contact with the cylinder.

As described above, according to the present invention, it is possible to prevent malfunction due to foreign substances, to prevent malfunction of the viscometer due to curing of the fluid, to settle for a long time in the tank in which the fluid is stored, and to prevent the reliability from being lowered during measurement. It is effective to minimize the change of the measured value due to the external pressure change.
