The solution

Up to 140,000 litres of wastewater shoot into the settling tank every minute. The surface is extremely turbulent, sometimes forming thick, sticky foam.

The non-contact radar sensor VEGAPULS WL 61 with plastic encapsulated sensor with protection rating IP 68 is well suited to this harsh environment and the perfect solution for measuring the level here. The density of the medium, the suspended solids and even the heavy foam have no influence on the accuracy of the measurement. The sensor detects all possible filling statuses reliably and with millimetre precision. 
Because of its high accuracy, VEGAPULS WL 61 even regulates the inflow of fresh water to compensate for evaporation.
Manual cleaning of the sensor is not necessary.
