The Avocet Sludge Blanket monitors sedimentation and scum accumulation in remote settlement tanks and clarifiers in water treatment works, waste water reclamation works and factories with treatment plant.

Particularly suited for identifying auto-desludging and overspill alarm signals and for monitoring the general biological health of thick sludge blankets. Gives highly accurate measurements of sludge blanket composition in settlement tanks and clarifiers by utilising extremely high frequency ultrasound sensors (1.1MHz) that can detect the lowest sludge density found in secondary clarifiers.
