Powerful Signal Processing
Defining sludge blanket interfaces is quite a complex task, especially as secondary algorithms and multiple interface layers can cause confusion. The Avocet utilises a range of powerful processing algorithms that the user can programme to generate the optimum sludge return signal.
To aid the user, the Avocet allows the user to view the raw return echoes from the clarifier so he/she can tailor the signal processing algorithms to maximise performance.
In secondary clarifiers sludge layers are often diffuse and difficult to detect. In such clarifiers the Avocet does the signal processing for you and it decides on what is the strongest sludge return echo by utilising extremely powerful mathematical techniques.
