Method and device enabling to measure in a precise, safe and automatic way the weighting content of a soluble component which contains a pulverulent product. The method is essentially characterized in that the respective quantities of the pulverulent product and the solvent which are introduced in the measuring container are controlled by weighting the container before and after their introduction in the container, and in that the result of the measurements is automatically corrected as a function of the weighting ratio between said quantities. The device comprises a handling robot (6) which displaces the measuring container (7) between a pulverulent product dispenser (1), electronic scales (2), a measuring unit (4) connected to a solvent feed unit (5) and a discharge tank (3). The operation cycle is regulated and controlled by an electronic computer (9). The invention may be applied particularly in a cement factory to measure the free lime content in the cement clinker. |
