• Reduction of the max. possible measuring range through buildup, above all of moist products.
• The respective lower group applies for very loose or loosened bulk solids.
The upper blocking distance (= UB) is the minimum distance from the reference point of the measurement
(mounting flange) to the maximum level.
R
LN
R = reference point of measurement
LN = probe length
UB = upper blocking distance
Blocking distance (factory setting):
• with rod and rope probes up to 8 m (26 ft): 200 mm (8 in)
• with rod and rope probes exceeding a length of 8 m (26 ft): 0.025 * (length of probe)
The specified blocking distances are preset on delivery. Depending on the application these settings can
be changed.
Within the blocking distance, a reliable measurement can not be guaranteed.
