Endress+Hauser Prosonic S Series - Nozzle Installation

Prosonic S FDU90/91/91F/92/93/95/96
14 Endress + Hauser
Nozzle installation Install the sensor 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°).
