Blocking distance
Function "upper block. dist" (059)
For rod probes and for rope probes with lengths of up to 8 m, the upper blocking distance is set to
0.2 m at the factory.
The upper blocking distance (= UB) is the minimum distance from the reference point of the
measurement (lower edge of the process connection) to the maximum level.
At the lowest part of the probe an exact measurement is not possible, see "Performance
characteristics" on
L00-FMP43xxx-17-00-00-en-001

Reference point of measurement, details
The blocking distance is preset to 0.2 m for rod probes. The blocking distance can be reduced if the
probe is mounted flush with the wall or in a nozzle, max. 50 mm in height.
When using a spray ball the blocking distance may not be smaller than 50 mm.
