Abstract
In centrifuges that concentrate liquids that contain suspended solids and wherein the concentrated solids are removed from the centrifuge at a constant rate, the concentration of solids leaving the centrifuge must be regulated. Some of the concentrated solids leaving the centrifuge for example can for this purpose be returned to the centrifuge. In the method in accordance with the invention, the solids leaving the centrifuge through its second outlet are diverted through a measuring channel that contains a bob. The shape of the bob ensures that the force exerted on it by the solids will increase with the viscosity of the solids. The force can accordingly be exploited to adjust a flow regulator in such a way that amount of solids returned to the centrifuge is decreased.
