CSO_OVERFLOW_MON
Combined-sewer-overflow spill detection with regulatory event counting, spill minutes and weir-formula volume.
When to use it
Use CSO_OVERFLOW_MON when a combined-sewer overflow, storm-overflow or emergency-overflow chamber is monitored by a level transmitter on the weir, and the operator has to report how many spills occurred, for how long, and to what volume.
