Input

The measured variable is the distance between the reference point and the product surface.
Subject to the empty distance entered "E" the level is calculated.
Alternatively, the level can be converted into other variables (volume, mass) by means of
linearization (32 points).
The following table describes the media groups and the possible measuring range as a function of
the media group.
