5.7.4 Assignment of current outputs
The function of outputs is different regarding which measuring function has been selected. It is
changing automatically if the measuring function has been changed as outlined in the following
table.
5.7.5 Measuring mode
The level measurement can be set in two different ways:
1. Height: The height of the sludge blanket/fluff measured from the bottom of the tank is dis-
played. Zero (resp. 4 mA) is at the bottom of the tank.
2. Depth: The depth of the sludge blanket/fluff measured from the liquid surface is displayed. Zero
(resp. 4 mA) is at the liquid surface or at the home position.
The height / depth ratio of the sensor is calculated in the following way:
Height /depth = maximum immersion depth (- blind zone) - start position.
