|
Process data
Measuring task:
Level measurement and point level detection
Measuring point:
Silo
Measuring range up to:
0 … 8 m
Medium:
Lime
Process temperature:
0 ... +30 °C
Process pressure:
1 … 3 bar
Special challenges:
Abrasion, caked deposits, silo internals
Application
In the nitrogen and phosphorus removal stage, lime is used to stabilize the pH value. Stored in silos, the lime is added to the wastewater as a solid or as an aqueous suspension. The silo content is measured by a radar sensor and a point level sensor detects the maximum level and transmits a full signal.
Your benefit
Reliable
Certain measurement even during filling
