The AquaScat measures turbidity of potable water according to IEC 27027 using 90+° scattered light detection in a free-falling water stream (models WTM, WTM A, HT). This contactless design eliminates window foiling and minimizes servicing to a minimum. Calibration check is performed with a calibration unit that is either mounted to perform the check or that is already built in (depending on variant).

APPLICATIONS

• Turbidity measurement in raw water
• Monitoring of flocculation and dosage of flocculants
• Filtration monitoring of filter performance and back-wash control
• Turbidity measurement in treated and final waters
• Turbidity monitoring of water in storage and distribution networks
• Turbidity measurement in process and waste waters
• • True non-contact measurement in free-fall stream (models WTM, WTM A, HT) making it virtually maintenance free
  • Dual beam measurement in optimized cell (model P)
  • Re-calibration with secondary standard (fully automatic at model WTM A)
  • Lowest stray light levels
  • Convenient operation via touch screen
  • Graphical display of trends and/or values
  • Visualization of measured values over the previous month
   
  SPECIFICATIONS
  • Measuring principle:
    90° Scattered light according to
    ISO 7027/EN27027
  • Light source: LED 880 nm

  • Resolution:
    0.001 FNU (WTM, WTM A, P); 
    0.1 FNU (HT)
  • Sample temperature: 0 .. +40 °C
  • Ambient temperature: –10 .. +50 °C
  • Operation: Touchscreen
  • Outputs:
    2 × 0/4 .. 20 mA, galv. isolated
    2 × Relays 250 VAC, 4A
  • Inputs:
    1 × for optional flow meter
    2 × 0/4 .. 20 mA
  • Digital interfaces: Ethernet, Modbus TCP, SD-card
  • Optional: Profibus DP, Modbus RTU
