Endress+Hauser’s new Turbimax CUS52D turbidity sensor monitors drinking and process water quality directly in the pipeline. This preserves and measures each drop of water with laboratory accuracy. Self-cleaning functions for unattended operation and smart calibration tools turn the sensor into a convenient and reliable water treatment package.
Turbimax CUS52D accurately and reliably (ISO7027) measures turbidity – even in the clearest water. As accuracy is independent of the installation environment, the optical sensor can be applied from inlet to outlet in all water production measuring points. Thus, the inline sensor continuously monitors the water quality with a precision that often even surpasses lab measurements.
Turbidity measurement without product loss
Thanks to its hygienic design, the CUS52D can be mounted directly into the pipeline. This eliminates the need for costly bypass installations and ensures that water and product losses are a thing of the past – what’s more, the sensor’s quick reaction time improves control of the treatment process. For quick integration into the process, the CUS52D features Memosens digital technology and factory calibration already on board. Automatic venting of the corresponding Flowfit CUA252 and CUA262 assemblies further simplifies operation.
Unattended operation
Air bubbles and contamination are everyday challenges in turbidity measurement, not with the CUS52D. Its special surface minimises the build-up of biofilms and particulates. In addition, with its ability to operate at high pressures (up to 10 bar), air bubbles are suppressed and with the optional air bubble trap, even the smaller air bubbles are caught. In particularly persistent cases, the CYR52 ultrasonic cleaning system removes surface contamination without direct product contact so that service intervals can be perfectly planned and the turbidity measurements run unattended over a long period of time.
Smart verification and calibration
Safety, both for employees and processes, is of the utmost importance. With this in mind, Endress+Hauser has developed smart solid-state references (CUY52) for the Turbimax CUS52D with which the sensor can be verified and calibrated risk-free. As a result, neither employees nor processes come into contact with any harmful liquids e.g. Formazin. The solid state references are ingeniously simple to use and provide reliable and clear results with every turbidity measurement.
