Important information for using this adapter
together with a SensoLyt armature:
Observe the following note when you want to use a
SensoLyt measuring armature with the aid of the adapter:
Warning
For safety reasons, use only electrodes especially
specified for high pressure and temperature loads (for
example pH combination electrode SensoLyt SEA-HP,
order no. 109 118). For more information, refer to the
YSI catalog or the Internet. YSI assumes no liability for
damages caused by using different electrodes.

General installation recommendations
Basic types of
installation
The optimum installation location must be individually deter-
mined for the type of sensor and the application.
Influential factors

B + Good flow
+ Low susceptibility to contamina-
tion
+ Low risk of membrane damage
TetraCon 700 IQ B + Good flow

tion
Check and adjust cell constants
after installation (see sensor op-
erating manual)
SensoLyt 700 IQ C + Good flow
+ Low susceptibility to contamina-
tion
- Danger of small stones damaging
the electrode
The enclosed fixing ring instead
of the protective hood improves
the incident flow.
Attention: It is no protection
against small stones!
The best incident flow is
achieved when the diaphragm
points against the flow direction.
TFK 700 IQ C + Good flow
+ Low susceptibility to contamina-
tion
The enclosed fixing ring instead
of the protective hood improves
the incident flow.

Note:
Please note the
special installation
recommendations
in the following
section.
A + Optimum flow of the sapphire disc
so there is no capture of air bub-
bles or large particles in front of
the sensor
- Susceptible to fibers getting
caught
- Risk of damage from stones and
abrasive particles
Optimum installation location
for measuring media without
contamination from fibers,
stones, or abrasive particles.
C + No risk of contamination by long fi-
bers
+ Low risk of damage from stones
and abrasive particles
- Susceptible to the capture of air
bubbles or large particles in front
of the sapphire disc (turbulence
effect)
In the case of contamination by
fibers, less prone to contamina-
tion than A.
B + Good flow of the sapphire disc, so
there is no interference from air
bubbles or large particles in front
of the sensor
- Risk of light reflections in narrow
containers
Good possibility in sufficiently
large containers or high values
of turbidity/total suspended sol-
ids.

Special installation recommendations:
VisoTurb 700 IQ and ViSolid 700 IQ
Note
Please also observe the general basic information in the
INSTALLATION chapter of the sensor operating manual. There
you will find important notes on optimizing the installation.
45 ° pipe installation
Pipe diameter at the installation location of at least DN 80.
The pipe should be straight and not tapered for a length
of at least 50 cm (VisoTurb 700 IQ) or 25 cm
(ViSolid 700 IQ) in the direction of observation. Angled or
tapered pipes can cause interference effects in the case
of low turbidity.
The front part of the sensor is pitched towards the flow.
Exception:
If there are high quantities of foreign bodies with fibrous
or large surfaces, as for example hairs, strings or leaves,
it may be of advantage to incline the sensor in the
direction of the flow so that the sapphire disc does not
face the flow.

The marking on the sensor shaft points towards the
pipeline. On page 9 you will find a description of how to
correctly align the sensor with the aid of a marking aid on
the sensor plug head connector.
90 ° pipe installation
Note
The 90 ° pipe installation is only suitable for large pipe
diameters and high turbidity/total suspended solids values
respectively. For other cases, the 45 °installation should be
preferred.
For installation, select a location with a pipe diameter as
big as possible.
Rotate the sensor so that the marking on the shaft (arrow
symbol) points in the direction of the pipe axis. On page 9
you will find a description of how to correctly align the
sensor with the aid of a marking aid on the sensor plug
head connector.

the correct position.
* The receiving tube for installation with the ADA-WA 1 is
included in the scope of delivery of the retractable
armature. For installation with the ADA-WA 4, use the
special (longer) receiving tube provided with the adapter in
order to ensure the correct length compensation.
