<p>A device (18) for measuring relative viscosity includes an apparatus (29) that can be movably mounted within a fluid reservoir (12) and a sensing system. The apparatus has two members (32, 34), with one member being more bendable than the other. When the apparatus is moving, the sensing system detects a differential bend between the members; the differential bend is related to the viscosity of a fluid when the fluid is included in the fluid reservoir in which the apparatus is movably mounted. The sensing system includes two spaced sensors (40, 42) which detect when magnets (36, 38) on the members pass the sensors. A timer provides a time lapsed between passage of one member past a sensor and passage of the other member past the other sensor. The time lapse is related to the viscosity of the fluid in the fluid reservoir. A controller controls the addition of a solvent to the fluid.</p> |
