Process data
Measuring task:
Level and pressure measurement
Measuring point:
Open basin and pipeline
Measuring range up to:
5 m
Medium:
Salt water
Process temperature:
+10 ... +40 °C
Process pressure:
0 ... 0 bar
Special challenges:
Agitated product surface, high accuracy
Application
To filter suspended matter out of the water, precipitants are added to the water. When small air bubbles are injected into the liquid, suspended matter is bound to the rising bubbles and drawn off at the water surface. In order to achieve the best possible bubble formation, the pressure in the air supply is regulated to stay within narrow limits. Reliable and accurate level measurement is necessary to achieve efficient removal of the suspended matter.
