Level Watch

Installation

A Finnish mineral processing plant uses Level Watch in order to predict froth collapse situations. In addition, the thickness information of the froth is used to stabilize the froth flotation process.

Prediction of froth collapses

Level Watch was able to detect changes in froth quantities 3 hours before the froth collapse occurred

Maintenance – no contamination problemsCase example

• CoreHydra demands very little

maintenance, because contamination does

not distract its measuring operations

• This is because change in the contact

impedance can be measured in real-time

• A Finnish mineral processing plant used

CoreHydra probe sensor for 9 months and

did not experience any measuring problems

caused by contamination

• Picture on the right illustrates the thickness

of contamination in CoreHydra probe after

9 months of use
