Anderson-Negele ITM-4DW Turbidity Meter

The Anderson-Negele ITM-4DW Turbidity meter is specifically designed for applications involving the measurement of water and other non-food liquids. It shares the key design elements of our ITM-4 turbidity meter used in dairy and food processing. It utilizes a dual-beam measuring system that provides long-term measurement performance with a minimal amount of maintenance. Key elements to the “DW” were to have a design that met the cost and operational requirements found in water monitoring. The “DW” uses a PPSU optics body that has been reduced in size for smaller line sizes to meet these needs. PPSU is widely accepted for use in water systems components as a material choice. The measuring area’s bore maintains sizing to the rest of the piping providing flow and measurement improvements. Installation and integration are simplified as the ITM-4DW has integral electronics in a watertight stainless steel enclosure. Outputs include an analog output for direct measurement and a programmable switched output for alarm or control. An input offers the ability to externally select measuring ranges to satisfy multiple measurement range needs on the fly.

  • Soiling of the optics is compensated
  • Compact device; separate evaluation unit not required
  • Units switchable between NTU and EBC (11 ranges each)
  • 4 freely selectable measurement ranges, externally switchable
  • Smallest measurement range 0…5 NTU or 0…1 EBC
  • Largest measurement range 0…5000 NTU or 0…1250 EBC
  • Smallest pipe diameter DN25
  • Colour-independent measurement (wavelength 860 nm)
  •  Switching output and analog output
