ABSTRACT:
A method and apparatus of controlling a rotating vacuum evaporation system is disclosed. The rotating flask, containing the medium to be evaporated, is buoyantly supported in a liquid bath and the relative elevation between the flask and the liquid level in the bath is measured. The relative elevation is utilized as the control signal to control the addition of fluid medium to the flask, and to shut off the system when desired.
