SLUDGE FINDER 2 PULSAR



Sludge Finder 2

The Sludge Finder 2 provides reliable and continuous sludge blanket level measurement. The two-part system has been purposely designed for sludge blanket level measurement, operating ultrasonically through a liquid. The Sludge Finder 2 uses proven echo processing algorithms to identify the sludge interface level using state of the art technology only found in this unit!

Sludge blanket level control is a crucial aspect of any process that includes primary settlement tanks, secondary settlement tanks, tertiary settlement tanks either with stationary or traveling bridges, clarifiers, gravity thickeners, or sequencing batch reactor systems. Sludge blanket level measurement works by measuring the distance between the sludge blanket surface and the water level. Once the sludge has reached the required density, the accompanying controller will then switch on the pumps and pump the sludge through into digesters, ready for the next treatment stage.

Effective sludge blanket level measurement can help treatment plants or industrial processes to generate their own electricity, ensure that pumps are being used efficiently, ensure that excess sludge is not being pumped into our local water sources, aids with compliance to health, safety, and environmental regulations, and finally, ensures that further sludge handling processes such as thickeners and dewatering equipment are all performing to their maximum with the correct concentration of sludge.

Features 

  • Continuous single or dual-channel level control
  • High-frequency gives high-reliability long term
  • Self-cleaning transducer removes the need for regular inspection
  • SBR tank applications can be monitored
  • Easy set-up via the drop-down menu on large clear display
  • The unit can track two different echoes with one transducer
  • Radio telemetry system - optional
