DERain overflow basin
Flood protection
To relieve the sewer network and sewage plant during heavy rains, on-site preflooders or rain overflow basins are deployed to absorb the fast-rising waters. Duration and strength of the flooding are measured in the basins. Since the preflooders and rain overflow basins are usually far away from the sewage plant, high priority is placed on installing absolutely maintenance-free measurement technology.
Level measurement with VEGAWELL 52
High precision and operational reliability are decisive for a reliable logging of the operating data from on-site preflooders or rain overflow basins. The suspension pressure transmitter VEGAWELL 52 provides both. The absolutely front-flush and abrasion-resistant ceramic measuring cell is continuously surrounded and therefore cleaned by the flowing water. Even extremely dirty water or mud cannot cause blockage of the measuring cell.
Indication and adjustment with VEGADIS 62
The VEGADIS 62 is an external indicating and adjustment unit. The 4 ... 20 mA/HART connection technology and variable mounting options in the field allow the unit to be installed at a distance of up to 1.5 km away from the sensor.
