Application
Turbimax CUS52D is a sensor for measuring turbidity and low solids content in
drinking water and process water applications.
• Turbidity measurement at all stages of the water treatment process
• Final turbidity measurement in outlet of waterworks
• Turbidity measurement in inlet of waterworks
• Turbidity measurement for filter monitoring and filter backwashing
• Turbidity measurement in drinking water networks
• Turbidity measurement in saline media (plastic sensor only)
Your benefits
• Turbidity measurement in accordance with ISO 7027
• The hygienic design with the 2" clamp means it can be mounted directly in pipes
and fits into CUA252 (PE 100) and CUA262 (stainless steel) flow assemblies
• Immersion version can be installed in open channels and basins
• Can be used at high temperatures and high pressures
• Standardized communication (Memosens technology) enables "plug and play"
• Intelligent sensor - all characteristics and calibration values are stored in the
sensor
• Customer calibrations with 1 to 6 points can be performed in the lab or at place of
installation
• Completely safe, as the optical source requires little power to operate
