The ultrasound cleaning system ensures low maintenance and longterm reliable measurement operation.
The ultrasound source integrated in the sensor excites the measurement windows to produce vibrations in the ultrasound range. The
movement of the surface as a result of this prevents the growth of
pollution in almost all cases and, thus, ensures reliable measured
values during continuous operation.
The sensor is designed to be equipped with an additional compressed
air-driven cleaning system, which supports the ultrasound cleaning
system as necessary.
1.3 Measuring principle of the UV-VIS sensor
The UV-VIS sensor operates according to the measuring principle of
UV-VIS spectrometry.
1 - 2
Any substance contained in a measuring solution attenuates a light
beam that penetrates the measuring solution. The attenuation (absorbance) of the light beam is measured for different wavelengths. The
wavelength dependent distribution produces the absorbance spectrum.
The wavelength range where an absorbance occurs is characteristic of
the substance. The extent of the absorbance depends on the amount
of the substance.
The influence of typical interference matrix variants occurring at municipal waste water treatment plants can be eliminated by including the
entire absorbance spectrum.
With this measuring principle, measuring does not take place continuously but at intervals.

1.4 Structure of the UV-VIS sensor
A UV-VIS sensor contains a light source (1), a measuring gap (3) to
enable the contact of light with the measuring solution, and a detector
(5) to measure the attenuated light beam.
The sender of the optical system (2) directs a light beam, the measuring
beam (6), through the measuring solution and a second light beam, the
reference beam (8), over a distance without measuring solution. The
test sample is between both measurement windows (3) in the
measuring gap.
The receiver of the optical system (4) directs the measuring beam and
reference beam to the detector. In the detector, the light is received by
fixed photo diodes.

3.3 Installation
3.3.1 Mounting the sensor
Note
The sensor is an optical precision instrument that is to be protected
against shocks. Make sure the distances to the wall, bottom and other
installation surroundings are sufficient. If necessary, protect the sensor
from hitting with the protective ring provided. Mount any fixing elements
only on the stable metal shaft.
Note
Always make sure the surface of the enclosure is not damaged by
sharp-edged objects. The enclosure of the sensor may not touch any
metallic objects in order to prevent contact corrosion.
Note
Do not suspend the sensor on the sensor connection cable. Risk of cable break and water penetration at the cable gland.
A wide range of mounting accessories is available for the installation of
the CarboVis 70x IQ TS (see chapter 6 S
EQUIPMENT, ACCESSORIES). Thus, all prevalent ways of mounting are
PARE PARTS, MAINTENANCE
possible.
Generally, observe the following general rules
when mounting the
sensor at the measuring location:
Horizontal installation When mounting the sensor horizontally, the measuring gap opening
should be on the side. Thus, any air bubbles can escape upward after
cleaning and no sediment can collect in the measuring gap. The sensor
should be aligned in parallel with the flow direction.
Fig. 3-1 Horizontal installation

ba75950e02 11/2012
CarboVis 70x IQ TS Commissioning
Flow direction
Vertical installation For vertical installation, mount the sensor in a position that allows inter-
fering elements in the measuring gap to escape with the current. In the
case of vertical installation, the minimum flow rate is 0.2 m/s so the
measuring gap is kept clean optimally.
Fig. 3-2 Vertical installation
Protection against shocks When installing the sensor, always make sure it cannot knock against
a wall or another obstacle. Make sure the safety margins are sufficient
(e. g. with suspended mounting).
Mount the enclosed shock protectors (see section 3.3.2). Their soft rubber compound absorbs hard impacts.

3.3.3 Connecting the sensor to the IQ SENSOR NET
Connection cable A sensor connection cable of the SACIQ or SACIQ SW type is required
to connect the sensor. The cable is available in different lengths.
Compared to the standard model SACIQ, the SACIQ SW sensor
connection cable is optimized regarding its corrosion resistance in
seawater and brackish water and adapted for use in conjunction with
the CarboVis 70x IQ TS . Information on this and other IQ S
ENSOR NET
accessories is given in the WTW catalog and on the Internet.
How to connect the SACIQ (SW) sensor connection cable to the terminal strip of an MIQ module is described in chapter 3 I

dry?
Before connecting the sensor and sensor connection cable, please
make sure the plug connections are dry. If moisture gets into the plug
connections, first dry the plug connections (dab them dry or blow them
dry using compressed air).
Note
Do not suspend the sensor on the sensor connection cable but use the
suitable mounting equipment. Information on this and other
IQ S
ENSOR NET accessories is given in the WTW catalog and on the In-
ternet.

3.4.2 Sensor structure
The physical sensor is the sensor with the instrument or model designation, CarboVis 70x IQ TS. The physical sensor processes the measurement signal (absorbance spectrum) and supplies up to 5
measurement results to the IQ S
ENSOR NET. The measurement results
are administrated like 5 sensors that differ in hierarchy as follows:
Main sensor The sensor for carbon measurement is the main sensor.
It registers on the system under the designation, CarboVis 70x IQ TS
and the series number of the physical sensor.
Secondary sensor The sensor for the measurement of total suspended solids is the
secondary sensor.
It registers on the system under the designation, SolidVis 70x IQ and
the series number of the physical sensor.
Virtual sensors All other sensors for carbon measurement are virtual sensors.
You register on the system under the designation, CarboVis 70x IQ TS
and the series number of the physical sensor.
