Froth Depth Detector

Supplier: Clean Process Technologies

The CleanProTech Froth Depth Detector (FDD) has been designed to provide flotation plant operators an accurate indication of where the froth/liquid interface is within their cells and as a result, the froth bed depth.

Price Guide: POA

Froth depth is a key control parameter for any flotation unit operation.


  • The unit is made from 316 stainless steel and provides the operating system with a 4-20 mA signal from a 10 to 30 VDC source.
  • No moving parts are immersed in the froth or liquid, meaning jams or blockages from solids build up are prevented.
  • A physical scale on the FDD can be easily read whilst viewing the unit, as well as a signal being sent to the control room.
  • The FDD can be adjusted for any depths required and can be custom fitted to any flotation cell.
