Level Measurement for Wastewater Collection Tanks

Accurately measure and control sewerage levels in intermediary vacuum sewerage stations.

Automate Sewage and Vacuum Pump Operations

After passing sump pits, household wastewater is sometimes transferred to a vacuum sewerage systems, which acts as an intermediary station between households and wastewater plants. Continuous measurement is needed in these tanks to ensure accurate vacuum- and sewer pump control. Once the sewage reaches a predetermined level, sewage pumps will initiate operation and transfer the sewage to wastewater plants. The vacuum pumps cycle on and off to maintain vacuum in the tank throughout this process.
