ABSTRACT:
A wire guided float level measurement system includes a float, a nozzle and an ultrasonic level detector which are attachable to an open frame. The float, which is supportable on a froth, is slideably attached to te frame via one or more guide wires, and the nozzle and ultrasonic level detector are fixed near the top of the frame. In operation the frame, with attachments, is disposed in a flotation cell in an upright position so as to traverse a froth layer which is formed in the cell. The float, while supported by the froth so as to follow the froth level, serves as a target for pulses transmitted from the ultrasonic level detector, and the detector continually measures the distance to the float which is an indirect indication of froth level. Any mineral accumulation on the float, which would interfere with its buoyancy, is washed off the top of the float by spraying wash water through one or more nozzles.
