2.4.1 Blocking distance, Nozzle mounting
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°).
