ViSolid®700 IQ (SW) Overview
1.4 Features of the ViSolid®700 IQ (SW)
Total suspended solids
measurement
The measurement of the total suspended solids in aqueous media with
®
the ViSolid
700 IQ (SW) is carried out as a scattered light
measurement. This records the suspended proportion of total
suspended solids (TSS).
Ultrasound cleaning
system
The ultrasound cleaning system ensures low maintenance and longterm reliable measurement operation.
The ultrasound source integrated in the sensor excites the front face
containing the measurement windows to oscillations in the ultrasound
range. The resulting movement of the surface prevents the growth of
pollution right from the start and, thus, ensures reliable measured
values during continuous operation.
AutoRange function Within the enormously large measuring range (0 - 40000 mg/l SiO2
and 0 - 40000 mg/l TSS depending on the measured material), the
AutoRange function selects the optimum resolution for the respective
measured value.
SensCheck function This monitoring function that is integrated in the sensor is used to
continually check the sensor function and to register any malfunctions
caused by the measuring medium. The correct operation of the
ultrasound cleaning system is also continuously monitored.

3.3 Installation
3.3.1 General information
®
The measuring principle of the ViSolid
700 IQ (SW) (scattered light
measurement) places specific requirements on the measurement
location and on the installation of the sensor.
If there is a low level of total suspended solids (< 2000 mg/l SiO2 or
< 1000 mg/l TSS), infrared light penetrates deep into the sample. Thus,
the measuring environment can have a significant effect on the
measured value displayed. Light that is reflected or scattered by the
ground or wall can strike the detector in the sensor and, thus, simulate
an increased level of total suspended solids.
Scattered light can be kept away from the measurement windows to a
great extent by favorable positioning of the sensor. Therefore, an
optimum installation position is particularly important for the
measurement of lower values of total suspended solids.
Note
Always maintain a distance of at least 10 cm from the ground and wall.
The following factors affect the measurement of the TSS contents:
Inclination of the sensor (see section 3.3.3)

Commissioning ViSolid®700 IQ (SW)
Sensor orientation around its longitudinal axis (see section 3.3.4)
Distances from the ground and wall (see section 3.3.5)
Light-colored, heavily light-scattering surfaces in the measuring
vessel (e.g. vessel inner surfaces) or in the measuring environment.
Unfavorable geometry of the measuring vessel or unfavorable
positioning of the sensor in the measuring vessel.
Spatial proximity of two optical sensors.
Very bright ambient light at the measuring location, e.g. direct
sunlight in the open channel

3.3.2 Flow direction
Generally, in flowing media, the measurement window should be
clearly pitched towards the flow (angle of incidence approx. 20 to 45 °).
Exception:
If there is a high proportion of foreign bodies with fibrous or
flat profiles such as, e.g. hair, twines or foliage, it can be advantageous
to tilt the sensor in the direction of flow so that the measurement
window is turned away from the flow.
3.3.3 Sensor angle

Note
Scattering and reflection are lowest at a sensor angle of 45° and at a
minimum distance of 10 cm to the ground and walls (see section 3.3.5).

Fig. 3-2 Direction of the infrared beam relative to the marking
The angle of incidence to the ground and walls can be affected by
rotating the sensor around its longitudinal axis. The sensor should be
turned so that as little light as possible that is scattered or reflected by
the wall or ground strikes the measurement window again.

3.3.5 Distances from the ground and wall
Note
If there is a low level of total suspended solids (< 2000 mg/l SiO2 or
< 1000 mg/l TSS), the effects of the measurement environment can
simulate a higher content of total suspended solids. The effect of the
measurement environment can be reduced by ensuring the optimum
conditions (see section 3.3.1).
The following graphic indicates the minimum distances of the
measurement windows to the ground or wall, which must be observed.
The effect of the distances on the measured value has been
determined for various wall materials (aluminum, black plastic) in the
case of a sensor placed vertically to the wall in drinking water or water
with 1000 mg/l SiO2.
ba76040e02 07/2013
Fig. 3-3 Effect of ground and wall distances on the measurement of TSS
Note
At low levels of total suspended solids, a minimum distance of at least
10 cm must be kept from the ground or wall.
Note
If an optimum installation is not possible due to the structural conditions
at the measuring location (e.g. in narrow pipelines), the effects of the
measurement environment can be compensated by user calibration
(see section 4.2.4).

3.4 Installation examples
As a rule, the ViSolid®700 IQ (SW) will measure interference-free
when the distances and angles etc. specified are observed. However,
interferences at the measuring location (see section 3.3.1) may require
special adaptations of the installation.
3.4.1 Measurement in an open pool or channel
Measurement in a pool The total suspended solids sensor can be suspended in the pool on a
chain (e.g. with EH/F 170 swing mounting assembly and EH/U 170
sensor holder). Make sure the sensor cannot bump against any walls
or obstacles.
Alternatively, the sensor can be immersed in the sample using a
pendulum mounting assembly, e.g. EH/P 170 pendulum mounting
assembly, (please note the minimum immersion depth).
