Abstract

Kinetic energy controller, for the treatment of a medium in a container, characterized by means for monitoring and controlling the weight of the contents of the container and producing an electrical signal indicative of the apparent variations in weight of the contents of the container, means for extracting from the electrical signal the portion of the signal produced by agitation of the medium in the container, means for registering said portion of the signal, and calibration means that correlate the characteristics of the medium, the time and the degree of agitation in the medium, whereby You can monitor the progress of the treatment.
