Pulsar Sludge Finder 2 sludge level measurement

Pulsar’s Sludge Finder 2 accurately measures interface levels in primary or secondary settlement tanks and SBR systems. Operating ultrasonically through liquid, the system uses echo processing algorithms to identify the sludge interface level using digital echo processing techniques.

The unit’s Viper transducer is immersed in the liquid, emitting a high-frequency ultrasonic pulse down towards the sludge interface.

The pulse reflects from the interface of the denser material back to the Viper transducer face. This echo is analysed by the controller unit providing a depth reading and an analog output proportional to the height of the interface above the vessel bottom.

The unit uses a self-cleaning underwater acoustic sensor that results in continuous, reliable sludge level measurement. It allows users to reduce sludge pumping and optimise dosing.

Applications include: primary and secondary settlement tanks; clarifiers; stationary and travelling bridge applications; gravity thickeners; reactor clarifiers; DAF thickeners; sequential batch reaction tanks and industrial process thickeners.
