SludgeWatch 715 - sludge blanket detector


The SludgeWatch 715 sludge blanket detector provides a simple and cost-effective way to pinpoint sludge levels in a wide variety of applications. The cable reel design eliminates the need for an additional carrying bag.

Reliable sludge level detection is essential to enable operators to remove sludge from tanks in a timely manner. Emptying the tank too often is cost inefficient and may affect the performance of other parts of the sludge treatment system. Similarly, leaving too much sludge in the tank may result in sludge being carried over to the next process step or into a local watercourse. Neither case is desirable, and the SludgeWatch 715 will provide a quick and easy sensor-based sludge level check, thus eliminating human error when estimating sludge thickness.

The SludgeWatch 715 sludge blanket detector uses a series of infrared sensors to detect sludge levels. Infrared suppression was chosen because it is ideal for detecting sludge present in the interface. It is usually much "thinner" than the sediment present at the bottom of the settling tank.

SludgeWatch 715 detector - easy to use

  •         The SludgeWatch 715 sediment thickness detector simplifies the process of finding a sediment layer by emitting an audible signal. The sediment layer is detected by immersing the sensor in the tank. The beeper will change and the LED will light up when the sensor reaches the layer.
  •         Simple on/off interface. No software or additional device needed to perform the measurement.
