Document Type and Number:
Japanese Patent JPH11506210
Kind Code:
A
Abstract:
A device for measuring relative viscosity includes a fluid reservoir, a stirrer, and a sensing system. The stirrer has two members, with one member being more bendable than the other. When the stirrer is moving, the sensing system detects a differential bend between the members; the differential bend is related to the viscosity of a fluid in the fluid reservoir. The sensing system includes two spaced sensors which detect when magnets on the members pass the sensors. A timer provides a time lapsed between passage of one of the members past a sensor and passage of the other member past the other sensor. The time lapsed is related to the viscosity of the fluid in the fluid reservoir. A controller automatically controls the addition of a solvent to the fluid within the fluid reservoir; the addition of the solvent is dependent on the time lapsed.
