3.3 Installing the sensor
3.3.1 Basic installation instructions
The electrode should be placed deep enough so that it always stays in the measuring media,
even when the level varies (see figure 3-1). The measuring ability of the electrode is influenced
negatively if the column of liquid to be measured is too large. For optimal results the column
should not exceed 300 mm / 12".
The sensor should be mounted in a vertical position. In some applications it may be desirable to
mount at a certain angle. In this case the angle from the horizontal plane should be greater than
or equal to 45°.
3.3.2 Mounting to MAA 2000 telescopic rod immersion holder
The mounting bracket of the telescopic rod is mounted to a handrail or a separate holder.
In case a handrail is not available, a mounting post with a vertical bar for sensor mounting can be
purchased from the manufacturer.
NOTE!
To protect the sensor from damage, the sensor should never be fully submerged into water.
Therefore a maximal immersion depth of 800 mm / 31" has to be maintained.
