Applications

  • Activated-sludge and MLSS monitoring
  • Wastewater treatment process control
  • Industrial process-water suspended-solids monitoring
  • High-solids sludge measurement
  • Marine or corrosive-water installations with suitable material selection

Installation & Integration

Choose the range according to expected solids concentration and sludge homogeneity. Position the probe in a representative flow zone and avoid deposits around the optical window. Specify material, cleaning, cable and transmitter requirements when requesting a quote.
