DESludge treatment
Return flow in the sludge pumping station
Different sludges settle out in the individual settling basins of a sewage plant. These sludges are removed from the basins by means of special pumps. During this process, the pressure in the pipes must be monitored and the pumps must be prevented from running dry.
Pressure measurement with VEGABAR 52
The pressure transmitters used in the pipes must be resistant to the abrasive sludge. VEGABAR 52 with frontflush ceramic CERTEC® measuring cell is particularly well suited for this application, since it is vibration proof and highly resistant to abrasion.
Pump dry run protection with VEGASWING 61
Due to the compact size of VEGASWING 61 and its only 40 mm long tuning fork, the instrument can be deployed at any desired location in the pipelines. The robust sensor delivers a clear switching signal and thus prevents pump overheating.
