Sludge Finder 2

Pulsar’s Sludge Finder 2 is a controller and transducer system that provides reliable continuous sludge blanket level measurement. It is used in thousands of applications worldwide for detecting sludge blanket levels in primary, secondary, tertiary settlement tanks either with stationary or travelling bridges, clarifiers, gravity thickeners or sequencing batch reactor (SBR) systems.

The two-part system includes a Viper Transducer which is purposely designed for sludge blanket level measurement. This purpose-built sludge level sensor uses sonar technology it is submersed into the liquid and detects the echoes from the material – any distinct density changes are reflected back to the transducer, the time taken for the echo to return is transmitted to the controller and the distance to the interface is calculated.

Features

  • Self-Cleaning Viper Sludge Sensor
    The Viper sludge transducer can be positioned up to 200m (656ft) from the controller and has a measurement range of 0.3m to 10 metres (0.98 – 32.8ft) – accuracy is 0.25% of the measured range. A tight 6° beam angle makes confined or cluttered applications easy and the self-cleaning face removes the need for regular inspection and maintenance – meaning you can avoid that unhygienic and hazardous task you hate!
  • Easy Set-up
    The Sludge Finder 2 controller is easy to install by following the on-screen menu driven set-up – simply follow the screen prompts to enter your application parameters and then the system automatically tracks the sludge blanket interface.
  • Flexible – User Specific
    Sludge Finder 2 offers a wealth of different options depending on requirements for your application
