Device for measuring screen mesh coefficient of polyacrylamide

The utility model discloses a device for measuring the screen mesh coefficient of polyacrylamide. The device comprises a glass tube body, an upper scale mark and a lower scale mark, wherein a spherical liquid containing cavity is arranged in the middle of the glass tube body; the upper scale mark and the lower scale mark are respectively and horizontally arranged on the peripheral surface of the glass tube body above and under the spherical liquid containing cavity; a spherical buffer cavity is arranged on the glass tube body above the upper scale mark, and a valve is arranged on the glass tube body under the lower scale mark. The device has the advantages that the device is specially designed for measuring the screen mesh coefficient of the polyacrylamide; when the device is used for measuring the screen mesh coefficient, the liquid level is adjusted to the position of the upper scale mark by the valve after a sample solution is sucked into the spherical liquid containing cavity, the valve is closed and the liquid level of the sample solution is stable, and the flow speed of the sample solution can be measured by opening the valve, so that the accuracy of the measurement for the screen mesh coefficient of the polyacrylamide can be guaranteed, and the working efficiency of the measurement operation is improved.
