VISCOSITY-MEASURING METHOD AND VISCOSITY-MEASURING INSTRUMENT

摘要

PROBLEM TO BE SOLVED: To provide a viscosity-measuring method reduced in measurement errors (dispersion) inclusive of the individual difference of a measuring person, capable of controlling the viscosity of a fluid with a satisfactory accuracy and capable of continuously using a viscosity-measuring instrument easy that is to wash in an on-the-spot work, and to provide the viscosity-measuring instrument.;SOLUTION: The viscosity-measuring method has a rotation detecting process for detecting the rotational speed of a motor (air motor using pressurized air with definite pressure as a drive source) for rotationally driving a pump for circulating the fluid (gravure printing ink) that is stored in a fluid tank (an ink pan and an ink tank) through piping and a viscosity calculation process which performs calculation of converting the rotational speed into viscosity and to output the viscosity. The viscosity-measuring instrument, to which this method has been adapted, is also disclosed.;COPYRIGHT: (C)2008,JPO&INPIT
