ABSTRACT:
A process for the continuous measurement of the density of a liquid by means of an aerometer body swimming in the liquid is characterized by the feature that the liquid is allowed to flow periodically at an increased flow rate past the aerometer body in order to clean the same of foreign matter, gas bubbles or the like disturbing the measuring, with the measuring procedure being interrupted during this cleaning period. In an apparatus for performing this process, an aerometer body is surrounded in a measuring vessel by a partition wall at a small distance therefrom, and line is provided, through which liquid to be measured may be introduced at a relatively high flow rate into the space between the aerometer body and the partition wall in order to periodically clean the aerometer body.
