  • Method and apparatus for measuring the level of liquids or agitated charges in vessels
    Patent number: 4583401
    Abstract: At the point or points in a vessel (1) at which the liquid or agitated charge level is to be monitored, a heat stream is fed into or out of the interior of the vessel (1) via a heat-conducting element (2) which is in thermal contact with the interior of the vessel (1) on the one hand and with a heat source or cold source (4) on the other hand. In order to indicate the level, the change in the heat stream when the liquid or agitated charge comes into contact with the elements (2) is determined by measuring the temperature of the element in the region of contact by means of a temperature sensor (5).
