Application

The Memosens CCS53E sensor is used for total chlorine measurement in:

• Wastewater treatment plants (disinfection monitoring and reuse).
• Process water and utilities (chlorine detection in cooling towers).
• Food and beverage industry (hygienic filling and washing water).
• Drinking water (ensuring adequate disinfection without overdosing).
• Swimming pools (efficient disinfectant dosing).

Operating limits

• Ambient temperature range: –20 to 60 °C (–4 to 140 °F)
• Storage temperature range:
  • Long-term storage (up to 2 years max.): 0 to 35 °C (32 to 95 °F) (non-freezing).
  • Short-term storage (up to 48 h max.): 35 to 55 °C (95 to 131 °F).
  • Without electrolyte: –20 to 60 °C (–4 to 140 °F).
• Process temperature range: 0 to 55 °C (32 to 130 °F), non-freezing.
• Process pressure: Up to 1 bar relative (14.5 psi relative) (2 bar absolute (29 psi absolute)).
• pH range: 4 to 9

Feed water

• Conductivity: Suitable for media with very low conductivity, such as demineralized water.
• Flow limits (in Flowfit CYA27 assembly):
  • Minimum volume flow (5 l version): 5 l/h (1.3 gal/h)
  • Minimum volume flow (30 l version): 30 l/h (7.9 gal/h)
