ABSTRACT:
The invention relates to a device in viscosity meters for measuring the viscosity of liquid having a large number of contaminants and a low viscosity, the meter including an inner cylinder (5) rotatably mounted in a stationary, outer cylinder (1) in a liquid projecting from a drive unit (12), there being a gap (4) forming a measuring zone between the cylinders (1,5) liquid being propelled through the gap with the aid of a propeller (3) arranged in front of the inner cylinder (5) and in a cavity (10) in the outer cylinder (1). The inner cylinder (5) is provided with an edge (6) projecting out into the gap (4) and the outer cylinder (1) has at least one slot (7) extending in its longitudinal direction and in the flow direction of the liquid, for enabling discharge of the contaminants fastening between the edge (6) and the outer cylinder (1), a self-cleaning strainer system thus being achieved, where the particles in the liquid only negligibly disturb measurement.
