Sludge Blanket Level


Sludge Blanket Level


Applications: Wastewater, Industrial Water.

Optimize sludge extraction, manage recirculation, and be warned of potential solids washouts or process upset by continuously measuring the sludge blanket level. The digitized probe eliminates interferences and comes with an automatic temperature compensation and position sensor. The probe comes with automatic temperature compensation and position sensor, and must be connected to an sc200 or sc1000 Controller to form a complete system. Note: For graphical display of sludge profile, the SONATAX sc probe must be connected to an sc1000 controller.
