Description

technical field [0001] The invention belongs to the technical field of measuring equipment, and in particular relates to an automatic verification device and method for a standard capillary viscometer. Background technique [0002] In the field of viscosity measurement in my country, the standard capillary viscometer is the main standard device of the capillary viscometer standard device. Whether its value is accurate or not is related to the entire viscosity value transmission system. The accuracy of the standard capillary viscometer directly affects the secondary standard viscosity The measurement accuracy of liquid, working capillary viscometer, outflow cup viscometer and falling ball viscometer will affect the viscosity measurement results of the measured fluid. The automatic verification device of the standard capillary viscometer is the premise to ensure the viscosity value. [0003] A standard capillary viscometer consists of an inlet tube, a vent tube and a measuring...
