A configuration capable of suppressing a variation in the measurement result of a falling body viscometer is proposed. Provided is a method of sending a falling body of a falling body viscometer when sending the falling body loaded in a loading unit of a loading holder into a measured substance, in which the falling body of the falling body viscometer is sent out in a manner such that the falling body is sent out from the loading unit by pressing the falling body using an extruding pin, thereby suppressing a variation in the measurement result.

Method for sending a falling body in a falling-body viscometer, falling-body sending device, and falling-body viscometer provided therewith

A novel configuration for a falling body viscometer using an electromagnetic induction sensor, wherein the time at which a falling body passes through the electromagnetic induction sensor can be specified with enhanced accuracy. This enables the falling speed of the falling body and in turn the viscosity of a fluid to be measured with increased accuracy. A falling body viscometer is provided with a first pair of coils located at the outer periphery of a measuring container so as to be separated from each other in the vertical direction, and also with a second pair of coils located at the outer periphery of the measuring container so as to be separated from each other in the vertical direction and to be located below the first coil pair, a specified distance away therefrom.

Falling speed measuring sensor for falling body viscometer and falling speed measuring method

A technique used to determine a falling state of a falling body, such as whether the falling body reaches a falling termination speed and falls uniformly or falls with a change in the speed is provided. In particular, a method of determining a falling state of a falling body passing through a measured substance inserted into a measuring container is provided, the method including: measuring a first elapsed time which is a time interval between extreme values of two potentials generated in a first coil pair when the falling body passes through the first coil pair and a second elapsed time which is a time interval between extreme values of two potentials generated in a second coil pair when the falling body passes through the second coil pair; and determining the falling state of the falling body by comparing the first elapsed time with the second elapsed time.
