5 Installing the OTT ecoN
The OTT ecoN can be installed in three different ways depending on the specific
application:
suspended in an observation well see 5.1
attached to a suitable substrate with fastening clips see 5.2
attached to a float see 5.3
With all installation types, note the following:
the optical path must always be completely under water;
there must be an unobstructed inflow of water in the optical path;
the inflow direction should be at right-angles to the optical path (see Figure 3);
the connecting cable may not be used for attaching or suspension; it may not
be subjected to any mechanical load in addition to its own weight!
contact between the sensor and the ground is to be avoided; risk of damage.
installation should be carried out in such a way that the OTT ecoN can be tem-
porarily uninstalled for maintenance without excessive work;
the measuring windows must be completely free of air bubbles after immersion;
the salt content of the water to be measured may not exceed 1 PSU
