Operating ultrasonically through liquid, Sludge Finder uses sophisticated and well proven echo processing algorithms to identify the sludge blanket level.

Level Transducer | Continuous Measurement - Sludge Finder's transducer is immersed in the liquid, emitting a high frequency sound pulse down towards the sludge interface. The pulse reflects from the interface of the denser material back to the transducer face.

This echo is analysed by the controller unit providing a depth reading and an analogue output proportional to the height of the interface above the vessel bottom.

  • Reduce sludge pumping
  • Eliminate potentially unhygenic manual measurements
  • Automate Clarifier/Thickener control
  • Advance process upset warning
  • Multiple tank options
  • Optimise chemical dosing

Level Transducer | Continuous Measurement - Sludge Finder uses a self-cleaning underwater acoustic sensor that results in continuous, reliable sludge level measurement. You can reduce sludge pumping, optimise dosing and let your staff concentrate on other things.

Use Level Transducer | Continuous Measurement - Sludge Finder in:

  • Primary and secondary clarifiers
  • Round and rectangular tanks
  • Stationary and travelling bridge applications
  • Gravity thickeners
  • Reactor clarifiers
  • DAF thickeners
  • SBR tanks
  • Industrial process thickeners

Multiple tanks

Level Transducer | Continuous Measurement - Sludge Finder will operate with up to four transducers from a single control unit, providing economical control and a single connection point for control system interface.

Level Transducer | Continuous Measurement - Sludge Finder features a 32-bit microprocessor with a multifunction display showing blanket level, complete tank profile, alarm points, tank depth and multiple tank status.

The hygenic solution

Remote measurement with Level Transducer | Continuous Measurement - Sludge Finder means you can put an end to tedious, time consuming, potentially unhygenic and hazardous manual measurements using gap switches or vacuum probes

Easy installation & set-up

Level Transducer | Continuous Measurement - Sludge Finder is simply installed using removable Phoenix connectors for all transducers and outputs, and the standard 6m transducer cable is simply extended with standard twin pair screened cable (Eg Belden 8162). Options include backing plate for handrail installation of the controller and a flexible skimmer avoidance mechanism.

To program Level Transducer | Continuous Measurement - Sludge Finder, the operator enters the tank depth and zero adjust parameters via a simple menu driven operator interface and the Level Transducer | Continuous Measurement - Sludge Finder automatically sets the system gain and tracks to the blanket interface, holding the outputs until the blanket level has been confidently established.

Self-cleaning transducer

Level Transducer | Continuous Measurement - Sludge Finder is designed to be maintenance free. The Level Transducer | Continuous Measurement - Sludge Finder transducer is a single beam ultrasonic unit immersed in the liquid. A replaceable rotary PVC wiper blade is in continuous contact with the transducer face, ensuring that the transducer face remains clean. The transducer may be positioned up to 500m from the control unit and has a measurement range of 0.3 to 50m.Accuracy is approximately ±0.03m. A tight 6° beam angle and sophisticated echo processing algorithms makes sure that the Level Transducer | Continuous Measurement - Sludge Finder deals with difficult tanks and rotating equipment with ease.

Versatile outputs

Level Transducer | Continuous Measurement - Sludge Finder features 4-20mA isolated outputs for each channel, with multi-drop RS485 connection, also isolated up to 1500V AC. Four control relays are included (10A rated), independently assignable to any channel. Change-over Loss of Echo (LOE) relay alarm is also included.
