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.
Media group DC (e )

1 1.4...1.6
2 1.6...1.9
3 1.9...2.5
4 2.5...4
5 4...7

1) not divisible up to 4 m (13 ft), divisible up to 6 m (20 ft)
Reduction of the max. possible measuring range through buildup, above all of moist products.
The upper blocking distance (= UB) is the minimum distance from the reference point of the measurement
(mounting flange) to the maximum level.

R = reference point of measurement
LN = probe length
