FALLING SPEED MEASURING SENSOR FOR FALLING BODY VISCOMETER AND FALLING SPEED MEASURING METHOD

Title:

FALLING SPEED MEASURING SENSOR FOR FALLING BODY VISCOMETER AND FALLING SPEED MEASURING METHOD

Document Type and Number:

WIPO Patent Application WO/2010/035418

Kind Code:

A1

Abstract:

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 (A) (coils 3, 4) located at the outer periphery of a measuring container (40) so as to be separated from each other in the vertical direction, and also with a second pair of coils (B) (coils 5, 6) located at the outer periphery of the measuring container (40) 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.
