Radar Gauge
MOUNTING THE GAUGE NOTE
If the electronics housing needs to be rotated, do not un-bolt the
adapter-to-housing bolts! Either un-bolt the flange bolts or the
adapter-to-flange bolts and rotate as needed. If the housing is rotated at the
housing-to-adapter connection, the gauge will be irreparably damaged, and
the warranty invalidated. (See Figure 2-17.) Flange bolts are suggested for
use; performance may be affected if adapter bolts are used.
Figure 2-17. Rotating the
Electronic Housing
Mount the radar gauge vertically on a 2-, 3-, 4-, or 6-inch ANSI Class
(DN 50, DN 80, DN 100, or DN 150) flange on top of the vessel. Make sure
only qualified personnel perform the installation.
NOTE
To ensure long life for your radar gauge, and to comply with hazardous
location installation requirements, tighten covers on both sides of the
electronics housing to achieve metal-to-metal contact.
