Technical Information
Turbimax CUS52D
Turbidity sensor
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

Function and system design
Measuring principle
The sensor works using the 90° light scattering principle in accordance with ISO 7027 and meets all
the requirements of this standard (no divergence and a maximum convergence of 1.5°). The ISO
7027 standard is obligatory for turbidity measurements in the drinking water sector.
A0030701
1 Measurement in accordance with ISO 7027
Measurement is done using a wavelength of 860 nm.
Sensor monitoring
The optical signals are continuously monitored and analyzed for plausibility. If inconsistencies occur,
an error message is output via the transmitter. The function is disabled by default.
Applications
The formazine factory calibration is used as the basis for precalibrating additional applications and
optimizing them for the different media characteristics.
Application Specified operational range
Formazine 0.000 to 1000 FNU
Kaolin 0 to 150 mg/l
PSL 0 to 125
Diatomite 0 to 550 mg/l
To adapt to a specific application, customer calibrations can be carried out with up to 6 points.
During initial commissioning or calibration at the CM44x, select the appropriate application for
‣
your field of application.
Application Field of application Unit
Formazine Drinking water, process water FNU; NTU; TE/F; EBC; ASBC
Kaolin Drinking water, filterable matter, industrial water mg/l; g/l; ppm
PSL The calibration standard commonly used in Japan for drinking
water turbidity
Diatomite Mineral-based solids (sand) mg/l; g/l; ppm
(dough)
1 to 6 points can be calibrated for all applications.
NOTICE
Multiple scattering
If the specific operational range is exceeded, the measured value displayed by the sensor can
decrease despite increasing turbidity. The indicated operational range is reduced in the case of highly
absorbing (e.g. dark) media.
In the case of highly absorbing (e.g. dark) media, determine the operational range
‣
experimentally beforehand.

During factory calibration, each Calkit solid state reference is matched specifically to a special
CUS52D sensor and can be used only with this sensor. Therefore, the Calkit solid state reference and
the CUS52D sensor are permanently assigned (married) to one another.
The following Calkit solid state references are available:
• 5 FNU (NTU)
• 20 FNU (NTU)
• 50 FNU (NTU)
The reference value indicated on the Calkit solid state reference is reproduced with an accuracy of
± 10% when the sensor is operating correctly.
The CUY52 solid state reference with approx. 4.0 FNU/NTU is used to check the function of any
CUS52D sensors. The standard is not assigned to a specific sensor and delivers measured values in
the range of 4.0 FNU ± 1.5 FNU/NTU with all CUS52D sensors.
A0035755
5 Solid state reference
Calibration vessel
The CUY52 calibration vessel allows the sensors to be validated quickly and reliably. This makes it
easier to adapt to the actual measuring point by creating basic conditions that are reproducible (e.g.
vessels with minimal backscattering, shade from interfering light sources etc.). There are two
different types of calibration vessel into which the calibration solution (e.g. formazine) can be
transferred.
A0035756

Communication and data processing
For detailed information on calibration tools, see BA01309C
Communication with the transmitter
Always connect digital sensors with Memosens technology to a transmitter with Memosens
technology. Data transmission to a transmitter for analog sensors is not possible.
6 Endress+Hauser
Turbimax CUS52D
Digital sensors can store measuring system data in the sensor. These include the following:
• Manufacturer data
• Serial number
• Order code
• Date of manufacture
• Calibration data
• Calibration date
• Number of calibrations
• Serial number of the transmitter used to perform the last calibration
• Operating data
• Temperature application range
• Date of initial commissioning
Dependability Maintainability
Easy handling
Sensors with Memosens technology have integrated electronics that store calibration data and other
information (e.g. total hours of operation or operating hours under extreme measuring conditions).
Once the sensor has been connected, the sensor data are transferred automatically to the transmitter
and used to calculate the current measured value. As the calibration data are stored in the sensor,
the sensor can be calibrated and adjusted independently of the measuring point. The result:
• Easy calibration in the measuring lab under optimum external conditions increases the quality of
the calibration.
• Pre-calibrated sensors can be replaced quickly and easily, resulting in a dramatic increase in the
availability of the measuring point.
• Thanks to the availability of the sensor data, maintenance intervals can be accurately defined and
predictive maintenance is possible.
• The sensor history can be documented on external data carriers and in evaluation programs.
• Thus, the current application of the sensors can be made to depend on their previous history.

Reference: measured value in recommended operational range, factory calibration

under analysis.
The measured error encompasses all inaccuracies of the measuring chain (sensor and
transmitter). However, it does not include the inaccuracy of the reference material used for
calibration.
For solids, the achievable measured errors depend very much on the media that are actually
present and may differ from the specified values. Extremely inhomogeneous media cause the
measured value to fluctuate and increase the measured error.

• Install the sensor in places with consistent flow conditions.
• The best installation location is in the ascending pipe (item 1). Installation in the horizontal pipe
(item 4) is also possible.
• Do not install the sensor in places where air spaces or bubbles occur (item 3) or where
sedimentation may occur (item 2).
• Avoid installation in the down pipe (item 5).
• Avoid fittings downstream from pressure reduction stages which can lead to outgassing.
Wall effects
Backscattering on the pipe wall may result in the distortion of measured values in the case of
turbidity values < 200 FNU. Therefore a pipeline diameter of at least 100 mm (3.9 in) is
recommended for reflecting materials (e.g. stainless steel). An assembly adjustment onsite is also
recommended.
Pipes made of stainless steel with diameter >DN 300 exhibit hardly any wall effects.
Black plastic pipes with diameter > DN 60 exhibit hardly any wall effects (<0.05 FNU). For this
reason, the use of black plastic pipes is recommended.
A0030704
12 Orientations for pipes and assemblies
• Install the sensor in such a way that the light beam is not reflected → 12, 10 (item 6).
• Avoid sudden changes in cross-section (item 9). Changes in cross-section should be gradual and
located as far away as possible from the sensor (item 10).
• Do not install the sensor directly downstream from a bend (item 7). Instead position it as far away
as possible from the bend (item 8).
