ABSTRACT:
A froth level monitor is disclosed. The froth level monitor comprises a plurality of electrically conductive electrodes spaced in the vertical direction and adapted to contact the top of the froth in sequence as the level of the froth rises, a constant current source connected to each electrode and capable of generating a constant current when its associated electrode is in contact with the froth, and a summing and time averaging current to voltage converter connected to the output of all the constant current sources for summing up all the currents as an indication of the number of electrodes in contact with the froth and for averaging with respect to time the variations in froth level so as to provide an indication of the mean level of the froth.
