Nozzle requirements
When installing the Rosemount 5900C with Parabolic Antenna on a 20 inch nozzle, the
nozzle height must not exceed 600 mm (24 in.). There has to be a free passage for the
radar beam within a 5° angle from the edge of the parabolic reflector to the lower end of
the nozzle.
The Rosemount 5900C should be installed so that the distance between flange and
product surface exceeds 800 mm (31 in.). Highest accuracy is obtained for product levels
below this point.
Nozzles with larger diameter may be higher than 600 mm (24 in.) as long as the
requirement of 5° free passage is fulfilled.
