Blocking distance,
nozzle installation
Install the Prosonic M at a height so that the blocking distance BD is not undershot, even at maximum fill level.
Use a pipe nozzle if you cannot maintain the blocking distance in any other way. The interior of the nozzle
must be smooth and may not contain any edges or welded joints. In particular, there should be no burr on the
inside of the tank side nozzle end. Note the specified limits for nozzle diameter and length. To minimise
disturbing factors, we recommend an angled socket edge (ideally 45°).

BD: blocking distance; SD: safety distance; E: empty calibration; F: full calibration (span); D: nozzle diameter; L: nozzle
length
Caution!
If the blocking distance is undershot, it may cause device malfunction.
Note!
In order to notice if the level approaches the blocking distance, you can specify a safety distance (SD). If the
level is within this safety distance, the Prosonic M outputs a warning or alarm message.
