Process data
Measuring task:
Level measurement
Measuring point:
Overflow basin
Measuring range up to:
0 … 5 m
Medium:
Rainwater
Process temperature:
+10 ... +30 °C
Process pressure:
0 … 0 bar
Special challenges:
Fouling, condensation, inundation
Application
Large Combined Sewer Overflows (CSOs) protect the wastewater treatment plant from a capacity overload during heavy rain. The precipitation is temporarily stored and then delivered to the treatment plant at a reduced rate. If the stormwater basin cannot hold the accumulating quantities of water, part of it is discharged. Due to legal requirements, such operational events and discharged water quantities must be measured and documented. A level sensor provides the required measurement data.
Your benefit
