DESewage pumping stations
Sewage on the way to cleaning
If the natural downward slope from residential areas to the sewage plant is not sufficient, it is increased by an appropriate amount through pumping stations. Level measurement in the sink is indispensable for guaranteeing smooth, cost-efficient operation of the pumps. Non-contact measurement is ideal here, because it keeps the sensor away from the heavily contaminated waste water and thus the maintenance requirements low. The often cramped installation conditions in the pump shafts are an additional challenge for the implemented measurement technology.
Level measurement in the pump shaft
In demanding measuring applications in pump shafts, where the high performance of radar technology makes a big difference due to the cramped conditions or the increased generation of foam, the radar sensor VEGAPULS WL 61 delivers reliable service.
For simple applications in pump shafts, the non-contact ultrasonic sensor VEGASON 61 is employed. It measures the level independently of sewage consistency and is completely maintenance-free.
Pump control with VEGAMET 391
The compact signal conditioning instrument VEGAMET 391 is ideal for simple, on-site control of the pumps. An integrated pump switching function allows optimal operation of smaller systems with up to four pumps without the expense of a separate control system.
