Installation instructions
Look at the construction drawing of the basin for a suitable position for the sensor. In doing so, you
must take the following factors into account:
• The minimum distance between the basin wall and the sensor is 45 cm (1.48 ft.) (sensor emits
ultrasound in conical form).
• There should not be any basin wall protrusions or piping in the measuring range below the sensor.
Scrapers that are only temporarily in this area are permitted.
• Do not install the sensor in zones in which air bubbles, turbulence, high levels of turbid material
or suspended matter or foam formation occur (e.g. inlet).
• Using an immersion tube, install the sensor 20 cm ( 0.66 ft.) beneath the surface of the water.
• The transmitter may not be installed in a second enclosure (heat accumulation).
• If possible, do not install the transmitter near high voltage sources. In addition, also avoid sources
of magnetic fields, e.g. large transformers or frequency converters.
• The system can only detect a separation zone if there is a clear transition between the zones.
Unclear transition from the liquid to the solid phase cannot be detected.

Device description Turbimax CUS71D

5 Device description

5.1 Sensor design

The sensor is designed for continuous in-situ determination of interfaces.
The sensor includes all necessary modules:
• Power supply
• Ultrasonic source sends the measurement signals.
• Ultrasonic receiver receives the measurement signals, digitalizes and converts the signals to a
measurement value.
• The microcontroller of the sensor controls the internal operations and the data transmission.
All data - including calibration data - are stored in the sensor. That means:
• A pre-calibrated sensor can be used at the measuring point.
• The sensor can be calibrated externally.
• The sensor can be used at multiple measuring points with different calibration data.

5.2 Measuring principle

A piezoelectric crystal is integrated in a flat cylindrical plastic housing. When the crystal is excited
by an electrical voltage, it generates a sonar signal. The ultrasonic waves are transmitted at a
frequency of 657 kHz at an angle of 6° to scan the separation zones.
The parameter measured is the time it takes for the transmitted ultrasonic signal to reach the solid
particles in the separation zone and return to the receiver.
A sensor version with wiper avoids film formation at the sensor membrane. If a turbidity signal is
also needed a sensor version with wiper and integrated turbidity measurement is available.

5.3 Function
The speed of the sound varies according to the physical properties of the measuring medium and is
affected by temperature and air pressure. The liquid zones and solids content of the medium also
vary.
To obtain precise measurement results, it is therefore vital to adapt system variables to the process,
e. g. pulselength and the speed of the sound.
The CM44x offers the following possibilities for signal evaluation:
• Mask out regions where the separation zone is not expected.
• Evaluate received signal strengths differently.
• Select leading or trailing signal edges in the evaluation.
• Amplify sensor signals at different rates, e. g. for floating sludge.
• Define a region (gate) above and below the separation zone. Signal evaluation only takes place in
the defined region. The gate wanders with the separation zone. This makes smoothing algorithms
unnecessary.
• Arrow indicator for basin floor.

5.4 Sensor monitoring

The optical signals are continuously monitored und checked for plausibility.
Discrepancies are reported via error messages by the transmitter.
The sensor check system of the Liquiline CM44x reports the following failure conditions:
• Implausible high or low measuring values
• Disturbed controlling due to erroneous measuring values

12 Endress+Hauser
Turbimax CUS71D Device description

5.5 Calibration

5.5.1 Factory calibration

The sensor is precalibrated when leaving the factory. After adaption of the basin parameters, the
sensor can be used in a wide range of applications without additional calibration.
The factory calibration cannot be deleted and can be retrieved at any time. All other calibrations -
performed as customized calibrations - are referenced to this factory calibration.

5.5.2 Calibration in the process

Sensor calibration in the process is performed by inputs at Liquiline CM44x (see BA451C/07/EN).

5.6 Cyclic cleaning

For cyclic cleaning a ultrasonic sensor with integrated wiper is available. The time interval is
selectable via software.

Endress+Hauser 13
Maintenance Turbimax CUS71D

6 Maintenance
You have to perform maintenance tasks at regular intervals.
We recommend setting the maintenance times in advance in an operations journal or log.
The maintenance cycle primarily depends on the system, the installation conditions and the
medium in which measurement takes place.

6.1 Cleaning the sensor

Sensor without wiper
Sensor fouling can affect the measurement results and even cause a malfunction.
The sensor must be cleaned at regular intervals to ensure reliable measurement results. The
frequency and intensity of the cleaning process depends on the medium.
Clean the sensor:
• As specified in the maintenance schedule
• Before every calibration
• Before returning the sensor for repair

! Note!
You must rinse the sensor thoroughly with water after cleaning.
Sensor with wiper
The time interval is selectable via software. The cleaning time interval depends on the medium. It
is recommended to replace the wiper once a year.
