Overview of the recommended installation locations
NoteAlways follow the INSTALLATION chapter of the respective sensor operating manual.
Sensor type Installation location (see figure on page 1-5)
Advantages (+) / Disadvantages (-) Conclusion / Comments
TriOxmatic 700 IQ,TriOxmatic 701 IQ,TriOxmatic 702 IQ,
B + Good incident flow+ Low susceptibility to contamination+ Low risk of membrane damage
TetraCon 700 IQ B + Good incident flow+ Low susceptibility to contamination
Check and adjust cell constants after installation (see sensor operating manual)
SensoLyt 700 IQ C + Good incident flow+ Low susceptibility to contamination- Danger of small stones damaging the
electrode
The enclosed fixing ring instead of the protective hood improves the incident flow.Attention: It is not a protection against small stones!The best incident flow is achieved when the junction points against the flow direction.

Overview of the recommended installation locations (continued)
Sensor type Installation location (see figure on page 1-5)
Advantages (+) / Disadvantages (-) Conclusion / Comments
VisoTurb 700 IQ, ViSolid 700 IQ
A + Optimum incident flow of the sapphire disc so there is no capture of air bubbles 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 fibers+ 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 contamination than A.
B + Good incident 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 solids.

EBST 700-DU/Napplication example
Application example of the EBST 700-DU/N in clear water (< 10 FNU):
Notes:The flow route in the area of the turbidity measurement should be installed vertically so that air bubbles can escape upwards.
The water should flow from the bottom up through the flow route (best evacuation of air bubbles).
If, due to the pressure decline in the configuration, the sample will probably outgas, we recommend to install a throttle valve above the measurement location.
With a low sample flow, we recommend to regularly empty the flow route.
