Provided is a new method to obtain a shear rate of a fluid and Provided are a program and a device for the method. In the method, a pair of vibrators (1,1) are vibrated by an electromagnetic drive (2) and a viscosity of the sample liquid (9) is calculated by measuring a driving current of a coil (2b), which has a step (S1) of calculating the viscosity (n) of the sample liquid (9), a step (S2) of calculating a driving force (F) on a center of a wet part of the vibrator from the driving current (I), and a step (S3) of calculating a shear stress (S) exerted on the sample liquid from the driving force (F) and a liquid contact area of the vibrator (A), wherein the shear rate (D) is calculated from a ratio between the shear stress (S) and the viscosity (S4). |
